This perf-focused refactoring moves the TNode's input / output initialization
logic to the first template pass - close to the place where directives are
matched and resolved.
This code change makes it possible to update-mode checks for both property
bindings and listeners registration.

`templateUrls` that do not point to actual files are now diagnosed as such
by the Language Service. Support for `styleUrls` will come in a next PR.
This introduces a utility method `getPropertyValueOfType` that scans
TypeScript ASTs until a property assignment whose initializer of a
certain type is found. This PR also notices a couple of things that
could be improved in the language-service implementation, such as
enumerating directive properties and unifying common logic, that will be
fixed in future PRs.

In ngcc's reflection hosts for compiled JS bundles, such as ESM2015,
special care needs to be taken for classes as there may be an outer
declaration (referred to as "declaration") and an inner declaration
(referred to as "implementation") for a given class. Therefore, there
will also be two `ts.Symbol`s bound per class, and ngcc needs to switch
between those declarations and symbols depending on where certain
information can be found.
Prior to this commit, the `NgccReflectionHost` interface had methods
`getClassSymbol` and `findClassSymbols` that would return a `ts.Symbol`.
These class symbols would be used to kick off compilation of components
using ngtsc, so it is important for these symbols to correspond with the
publicly visible outer declaration of the class. However, the ESM2015
reflection host used to return the `ts.Symbol` for the inner
declaration, if the class was declared as follows:
```javascript
var MyClass = class MyClass {};
```
For the above code, `Esm2015ReflectionHost.getClassSymbol` would return
the `ts.Symbol` corresponding with the `class MyClass {}` declaration,
whereas it should have corresponded with the `var MyClass` declaration.
As a consequence, no `NgModule` could be resolved for the component, so
no components/directives would be in scope for the component. This
resulted in errors during runtime.
This commit resolves the issue by introducing a `NgccClassSymbol` that
contains references to both the outer and inner `ts.Symbol`, instead of
just a single `ts.Symbol`. This avoids the unclarity of whether a
`ts.Symbol` corresponds with the outer or inner declaration.

All of the `pipeBind` instructions call into `isPure` and `unwrapValue` which in turn call `getLView` internally. These internal calls are redundant, because we already have the `LView` from the `load` calls just before it.

Before this refactoring we had 2 utility functions to check if a given
TNode has matching directives. This PR leaves just one such function
(one that does less memory read).

The instantiation of the resolver also requires instantiation of the
StaticReflector, and the latter requires resolution of core Angular symbols.
Module resolution should not be done during instantiation to avoid potential
cyclic dependency between the plugin and the containing Project, so the
Singleton pattern is used to create the resolver.

While determining a property name to bind to we were checking a mapping object
resulting in the megamorphic read. Replacing such read with a series of if checks
speeds up rproprty update benchmark ~30% (~1400ms down to ~1000ms).

Ensures that the "core_all:size_test" target runs with "--define=compile=aot".
This is necessary because we don't run this test on CI currently, but if we run
it manually, we need to ensure that it runs with Ivy for proper size comparisons.

Presumably, the size of the results array was checked so that a TS
source file wouldn't have to be created if there were no diagnostics.
However, it is very likely that a TS program already has the
`ts.SourceFile` for file when diagnostics are queried. This removal is
just to make the function a minimal amount simpler.
