This commit adds support for completions of properties on `$event`
variables in bound outputs.
This is the second major PR to support completions for `$event`
variables (https://github.com/angular/vscode-ng-language-service/issues/531).
The final completion support that must be provided is for `$event`
variables in bindings targeting DOM events, like `(click)`.
PR Close#34570
This commit makes `findOutputBinding` a utility function for the
language service, which will be used by the `expression_diagnostics`
module in #34570. Keeping the function in `locate_symbol` results in a
circular dependency between `expression_diagnostics` and
`locate_symbol`.

We had some logic for generating and passing in the `elIndex` parameter into the `hostBindings` function, but it wasn't actually being used for anything. The only place left that had a reference to it was the `StylingBuilder` and it only stored it without referencing it again.
PR Close#34969
Component's decorator handler exposes `preanalyze` method to preload async resources (templates, stylesheets). The logic in preanalysis phase may throw `FatalDiagnosticError` errors that contain useful information regarding the origin of the problem. However these errors from preanalysis phase were not intercepted in TraitCompiler, resulting in just error message text be displayed. This commit updates the logic to handle FatalDiagnosticError and transform it before throwing, so that the result diagnostic errors contain the necessary info.

For the structural directive, the 'path' will contain multiple `BoundDirectivePropertyAst` which depends on the number of directive property in the attribute value(e.g. '*ngFor="let item of []; trackBy: test;"', it has 2 `BoundDirectivePropertyAst`, 'ngForOf' and 'ngForTrackBy').

the test failures most likely result from the babel updates in the previous commit.
it does look like we lost the file path from the error message, which is something that we
should follow up no in a separate change.

Previously we relied on this package being hoisted and available, which is error prone and it would
be just a matter of time before the build would break due rehoisting of deps upon future npm package.json
changes.
PR Close#34974
It's not clear how this ever worked (npm hoisting is a suspect though), but this dep is required because
one of the tests imports @babel/generator in the ts sources.
The lack of this dep is breaking builds on the master branch.

As part of the effort to tighten the API surface of
`TypeScriptServiceHost` in preparation for the migration to Ivy, I realized
some recently added APIs are not strictly needed.
They can be safely removed without sacrificing functionality.
This allows us to clean up the code, especially in the implementation of
QuickInfo, where the `TypeScriptServiceHost` is leaked outside of the
`LanguageService` class.
This refactoring also cleans up some duplicate code where the QuickInfo
object is generated. The logic is now consolidated into a simple
`createQuickInfo` method shared across two different implementations.

Previously we would write to class/style as strings `element.className` and `element.style.cssText`. Turns out that approach is good for initial render but not good for updates. Updates using this approach are problematic because we have to check to see if there was an out of bound write to style and than perform reconciliation. This also requires the browser to bring up CSS parser which is expensive.
Another problem with old approach is that we had to queue the DOM writes and flush them twice. Once on element advance instruction and once in `hostBindings`. The double flushing is expensive but it also means that a directive can observe that styles are not yet written (they are written after directive executes.)
The new approach uses `element.classList.add/remove` and `element.style.setProperty/removeProperty` API for updates only (it continues to use `element.className` and `element.style.cssText` for initial render as it is cheaper.) The other change is that the styling changes are applied immediately (no queueing). This means that it is the instruction which computes priority. In some circumstances it may result in intermediate writes which are than overwritten with new value. (This should be rare)
Overall this change deletes most of the previous code and replaces it with new simplified implement. The simplification results in code savings.

This change introduces several functions for manipulating items in an array in an efficient (binary search) way.
- `arraySplice` a faster version of `Array.splice()`.
- `arrayInsert` a faster version of `Array.splice(index, 0, value)`.
- `arrayInsert2` a faster version of `Array.splice(index, 0, value1, value2)`.
- `arrayInsertSorted` a way to insert a value into sorted list.
- `arrayRemoveSorted` a way to remove a value from a sorted list.
- `arrayIndexOfSorted` a way to find a value in a sorted list.
- `ArrayMap` Efficient implementation of `Map` as an `Array`.
- `arrayMapSet`, `arrayMapGet`, `arrayMapIndexOf`, and `arrayMapDelete` for manipulating `ArrayMap`s.

NOTE: This change must be reverted with previous deletes so that it code remains in build-able state.
This change deletes old styling code and replaces it with a simplified styling algorithm.
The mental model for the new algorithm is:
- Create a linked list of styling bindings in the order of priority. All styling bindings ere executed in compiled order and than a linked list of bindings is created in priority order.
- Flush the style bindings at the end of `advance()` instruction. This implies that there are two flush events. One at the end of template `advance` instruction in the template. Second one at the end of `hostBindings` `advance` instruction when processing host bindings (if any).
- Each binding instructions effectively updates the string to represent the string at that location. Because most of the bindings are additive, this is a cheap strategy in most cases. In rare cases the strategy requires removing tokens from the styling up to this point. (We expect that to be rare case)S Because, the bindings are presorted in the order of priority, it is safe to resume the processing of the concatenated string from the last change binding.
