With this change we update several dependencies to avoid Renovate creating a lot of PRs during onboarding. We also remove yarn workspaces as after further analysis these are not needed.
Certain dependencies such as `@octokit/rest`, `remark` and `@babel/*` have not been updated as they require a decent amount of work to update, and it's best to leave them for a seperate PR.

This commit refactors the generated code for class metadata in partial
compilation mode. Instead of emitting class metadata into a top-level
`ɵsetClassMetadata` call guarded by `ngDevMode` flags, the class
metadata is now declared using a top-level `ɵɵngDeclareClassMetadata`
call.
PR Close#41200
This commit marks the `compilationMode` compiler option as stable, such
that libraries can be compiled in partial compilation mode.
In partial compilation mode, the compiler's output changes from fully
compiled AOT definitions to an intermediate form using partial
declarations. This form is suitable to be published to NPM, which now
allows libraries to be compiled and published using the Ivy compiler.
Please be aware that libraries that have been compiled using this mode
can only be used in Angular 12 applications and up; they cannot be used
when Ivy is disabled (i.e. when using View Engine) or in versions of
Angular prior to 12. The `compilationMode` option has no effect if
`enableIvy: false` is used.

`NgCompiler` previously had a notion of the "next" `ts.Program`, which
served two purposes:
* it allowed a client using the `ts.createProgram` API to query for the
latest program produced by the previous `NgCompiler`, as a starting
point for building the _next_ program that incorporated any new user
changes.
* it allowed the old `NgCompiler` to be queried for the `ts.Program` on
which all prior state is based, which is needed to compute the delta
from the new program to ultimately determine how much of the prior
state can be reused.
This system contained a flaw: it relied on the `NgCompiler` knowing when
the `ts.Program` would be changed. This works fine for changes that
originate in `NgCompiler` APIs, but a client of the `TemplateTypeChecker`
may use that API in ways that create new `ts.Program`s without the
`NgCompiler`'s knowledge. This caused the `NgCompiler`'s concept of the
"next" program to get out of sync, causing incorrectness in future
incremental analysis.
This refactoring cleans up the compiler's `ts.Program` management in
several ways:
* `TypeCheckingProgramStrategy`, the API which controls `ts.Program`
updating, is renamed to the `ProgramDriver` and extracted to a separate
ngtsc package.
* It loses its responsibility of determining component shim filenames. That
functionality now lives exclusively in the template type-checking package.
* The "next" `ts.Program` concept is renamed to the "current" program, as
the "next" name was misleading in several ways.
* `NgCompiler` now wraps the `ProgramDriver` used in the
`TemplateTypeChecker` to know when a new `ts.Program` is created,
regardless of which API drove the creation, which actually fixes the bug.

This commit changes the partial compilation so that it outputs declarations
rather than definitions for injectables.
The JIT compiler and the linker are updated to be able to handle these
new declarations.

The other similar interfaces were renamed in https://github.com/angular/angular/pull/41119,
but this one was left since it had existed before Ivy. It looks like the interface was
never actually exposed on npm so it is safe to rename this one too.

Currently, we throw a FatalDiagnosticError when we fail to load a resource
(`templateUrl` or `styleUrl`) at various stages in the compiler. This prevents
analysis of the component from completing. This will result in in users not being
able to get any information in the component template when there is a missing
`styleUrl`, for example.
This commit simply tracks the diagnostic, marks the component as poisoned, and
continues merrily along. Environments configured to use poisoned data
(like the language service) will then be able to use other information from the analysis.

Currently, fs-extra is used to delete a directory recursively, but this is already available in native Node.JS. Hence, making this dependency redundant.

This change introduces a new hook on the `ResourceHost` interface named `transformResource`.
Resource transformation allows both external and inline resources to be transformed prior to
compilation by the AOT compiler. This provides support for tooling integrations to enable
features such as preprocessor support for inline styles.
Only style resources are currently supported. However, the infrastructure is in place to add
template support in the future.

This enumeration will now start to appear in publicly facing code,

Each of the annotations had its own function for doing this, and those
methods were generally employing spread operators that could allow
unwanted properties to leak into the factory metadata object.
This commit supplies a shared function `toFactoryMetadata()` that
avoids this spread of properties into the returned function.

This instruction was created to work around a problem with injecting a
`ChangeDetectorRef` into a pipe. See #31438. This fix required special
metadata for when the thing being injected was a `ChangeDetectorRef`.
Now this is handled by adding a flag `InjectorFlags.ForPipe` to the
`ɵɵdirectiveInject()` call, which avoids the need to special test_cases
`ChangeDetectorRef` in the generated code.

A previous commit implemented a streamlined performance metric reporting
system for the compiler-cli, controlled via the compiler option
`tracePerformance`.
This commit adds a custom Bazel flag rule //packages/compiler-cli:ng_perf
to the repository, and wires it through to the `ng_module` implementation
such that if the flag is set, `ng_module` will produce perf results as part
of the build. The underlying mechanism of `//:ng_perf` is not exported from
`@angular/bazel` as a public rule that consumers can use, so there is little
risk of accidental dependency on the contents of these perf traces.
An alias is added so that `--ng_perf` is a Bazel flag which works in our
repository.

ngtsc has an internal performance tracing package, which previously has not
really seen much use. It used to track performance statistics on a very
granular basis (microseconds per actual class analysis, for example). This
had two problems:
* it produced voluminous amounts of data, complicating the analysis of such
results and providing dubious value.
* it added nontrivial overhead to compilation when used (which also affected
the very performance of the operations being measured).
This commit replaces the old system with a streamlined performance tracing
setup which is lightweight and designed to be always-on. The new system
tracks 3 metrics:
* time taken by various phases and operations within the compiler
* events (counters) which measure the shape and size of the compilation
* memory usage measured at various points of the compilation process
If the compiler option `tracePerformance` is set, the compiler will
serialize these metrics to a JSON file at that location after compilation is
complete.

TypeScript 4.2 has changed its emitted syntax for synthetic constructors
when using `downlevelIteration`, which affects ES5 bundles that have
been downleveled from ES2015 bundles. This is typically the case for UMD
bundles in the APF spec, as they are generated by downleveling the
ESM2015 bundle into ES5. ngcc needs to detect the new syntax in order to
correctly identify synthesized constructor functions in ES5 bundles.
