Previously the concept of multiple directives with the same selector was
not supported by ngtsc. This is due to the treatment of directives for a
component as a Map from selector to the directive, which is an erroneous
representation.
Now the directives for a component are stored as an array which supports
multiple directives with the same selector.
Testing strategy: a new ngtsc_spec test asserts that multiple directives
with the same selector are matched on an element.

These tests are not relevant to Ivy:
//packages/compiler-cli/test/diagnostics:check_types
//packages/compiler-cli/test/diagnostics:expression_diagnostics
//packages/compiler-cli/test/transformers:test
//packages/compiler-cli/test:extract_i18n
The //packages/compiler-cli/test:ngtools_api test has 2 specs, one of
which passes and the other of which depends on ngtsc supporting lazy
routes. It's now disabled with fixmeIvy().

These paths are no longer needed / used.
I had to disable one jit mode spec because it fails now that we actually run it.
I root caused the jit test failure as missing forwardRef support. See FW-645.

When ngtsc compiles @angular/core, it rewrites core imports to the
r3_symbols.ts file that exposes all internal symbols under their
external name. When creating the FESM bundle, the r3_symbols.ts file
causes the external symbol names to be rewritten to their internal name.
Under ngcc compilations of FESM bundles, the indirection of
r3_symbols.ts is no longer in place such that the external names are
retained in the bundle. Previously, the external name `ɵdefineNgModule`
was explicitly declared internally to resolve this issue, but the
recently added `setClassMetadata` was not declared as such, causing
runtime errors.
Instead of relying on the r3_symbols.ts file to perform the rewrite of
the external modules to their internal variants, the translation is
moved into the `ImportManager` during the compilation itself. This
avoids the need for providing the external name manually.

Now that the Ivy switch transform uses ts.getMutableClone() to copy
statements, there's no need to set .parent pointers on the resulting
updated nodes. Doing this was causing assertion failures deep in
TypeScript in some cases.

Make a copy of the ts.SourceFile before modifying it in the ivy_switch
transform. It's suspected that the Bazel tsc_wrapped host's SourceFile
cache has issues when the ts.SourceFiles are mutated.

In a more specific scenario: Considering people use a custom TypeScript compiler host with `NGC`, they _could_ expect only posix paths in methods like `writeFile`. This at first glance sounds like a trivial issue that should be just fixed by the actual compiler host, but usually TypeScript internal API's just pass around posix normalized paths, and therefore it would be good to follow the same standards when passing JSON genfiles to the `CompilerHost`.
For normal TypeScript files (and TS genfiles), this is already consistent because those will be handled by the actual TypeScript `Program` (see `emitCallback`).
