ayazhafiz 4ba478267e feat(language-service): specific suggestions for template context diags (#34751)
This commit elaborates diagnostics produced for invalid template
contexts by including the name of the embedded template type using the
template context, and in the common case that the implicity property is
being referenced (e.g. in a `for .. of ..` expression), suggesting to
refine the type of the context. This suggestion is provided because
users will sometimes use a base class as the type of the context in the
embedded view, and a more specific context later on (e.g. in an
`ngOnChanges` method).

Closes https://github.com/angular/vscode-ng-language-service/issues/251

Keen Yee Liau 6d28a209e4 test(language-service): Remove test cases from parsing-cases.ts (#34716)
This commit removes some test scenarios from `parsing-cases.ts` and
colocate them with the test code instead. This makes the tests easier to
read and understand.

Keen Yee Liau 2dffe65cfd fix(language-service): completions after "let x of |" in ngFor (#34473)
This commit fixes a bug in which we do testing for completions.
Subsequently, this exposes another bug in our implementation whereby
suggestions are not provided in "ngFor" where there should have been.

Currently, multiple test cases are grouped together in a single
template. This requires the template to be somewhat complete so that
test cases that depend on variables declared earlier would pass.

Consider the following example:

```
  template: `
    <div *ngFor="let ~{for-person}person of ~{for-people}people">
      <span>Name: {{~{for-interp-person}person.~{for-interp-name}name}}</span>
      <span>Age: {{person.~{for-interp-age}age}}</span>
    </div>`,
```

In order to test `~{for-interp-person}`, `people` has to be included after
`~{for-people}`. This means the test case for `~{for-people}` is not
reflective of the actual use case because the variable is already there!
In real case, the expression would be incomplete, and our implementation
failed to take that into account.

This commit breaks such test into individual tests, and fix the bugs in
the underlying implementation.

Keen Yee Liau a04f7c0d5f fix(language-service): Proper completions for properties and events (#34445)
This commit fixes autocompletions for properties and events bindings.

The language service will no longer provide bindings like (click) or [id].
Instead, it'll infer the context based on the brackets and provide suggestions
without any brackets.

This fix also adds support for alternative binding syntax such as
`bind-`, `on-`, and `bindon`.

Keen Yee Liau 5eaab85fc0 fix(language-service): Remove completions for let and of in ngFor (#34434)
`let` and `of` should be considered reserved keywords in template syntax
and thus should not be part of the autocomplete suggestions.

For reference, TypeScript does not provide such completions.

This commit removes these results and cleans up the code.

Keen Yee Liau 64aae3a9df test(language-service): test project cleanup (#33157)
This PR adds es2015 lib to the `tsconfig.json` of the test project so
that `Promise` could be used. Note this only affects diagnostics in the
IDE. The tsconfig in Language Service Mock Host is the actual config
values used, and it already has es2015 lib.

- Other minor cleanup: Rename imports in `main.ts`.
- Add more cases to `parsing-cases.ts`, which are tested in later PRs

Keen Yee Liau 9d8dc793da test(language-service): Create proper test project (#32653)
Language service uses a canonical "Tour of Heroes" project to test
various features, but the files are all contained in test_data.ts which
is hard to read and often contains errors that are difficult to catch
without proper IDE syntax highlighting. The directory structure is also
not clear from first glance.

This PR refactors the test project into standalone files in the proper
format.

Next up:
[ ] Update the interface of MockTypeScript to only accept scriptNames.
[ ] Remove test_data.ts
