Keen Yee Liau 7eccbcd30d fix(language-service): Make missing module suggestion instead of error (#34115)
If a Component or Directive is not part of any NgModule, the language
service currently produces an error message. This should not be an
error. Instead, it should be a suggestion.

This PR removes `ng.DiagnosticKind`, and instead reuses
`ts.DiagnosticCategory`.

Keen Yee Liau 39722df41e fix(language-service): Do not produce diagnostics if metadata for NgModule not found (#34113)
The language service incorrectly reports an error if it fails to find
NgModule metadata for a particular Component / Directive. In many cases,
the use case is legit, particularly in test.

This commit removes such diagnostic message and cleans up the interface
for `TypeScriptHost.getTemplateAst()`.

ayazhafiz 1425e63029 fix(language-service): determine correct type for ngFor exported values (#34089)
Currently, variables of an unknown type in an `*ngFor` expression are
refined to have the type of the iterable binding of the `*ngFor`
expression. Unfortunately, this is a bug for variables aliasing
[values exported by
`*ngFor`](https://angular.io/api/common/NgForOf#local-variables),
including `index` and `first`, because they are also given the type of
the binding expression, but they are not of the binding type. For
example, in

```typescript
@Component({
  selector: 'test',
  template: `
    <div *ngFor="let hero of heroes; let i = index; let isFirst = first">
      {{ hero }}
    </div>
  `
})
export class TestComponent {
  heroes: Hero[];
}
```

The local variables `i` and `isFirst` are determined to have a type of
`Hero`, when actually their types are `number` and `boolean`,
respectively.

This commit fixes this bug by checking if the value of a variable in an
`*ngFor` expression is known to be an export and assigning the variable
the type of that export value. Only if the variable does not alias an
export is it typed with the binding value of the `*ngFor` expression.

ayazhafiz 49804fe017 fix(language-service): determine index types accessed using dot notation (#33884)
Commit 53fc2ed8bf added support for
determining index types accessed using index signatures, but did not
include support for index types accessed using dot notation:

```typescript
const obj<T>: { [key: string]: T };
obj['stringKey']. // gets `T.` completions
obj.stringKey.    // did not peviously get `T.` completions
```

This adds support for determining an index type accessed via dot
notation by rigging an object's symbol table to return the string index
signature type a property access refers to, if that property does not
explicitly exist on the object. This is very similar to @ivanwonder's
work in #29811.

`SymbolWrapper` now takes an additional parameter to explicitly set the
type of the symbol wrapped. This is done because
`SymbolTableWrapper#get` only has access to the symbol of the index
type, _not_ the index signature symbol itself. An attempt to get the
type of the index type will give an error.

ayazhafiz 53fc2ed8bf feat(language-service): completions support for indexed types (#33775)
Previously, indexing a container type would not return completions for
the indexed type because for every TypeScript type, the recorded index
type was always marked as `undefined`, regardless of the index
signature.

This PR now returns the index type of TypeScript containers with numeric
or string index signatures. This allows use to generate completions for
arrays and defined index types:

```typescript
interface Container<T> {
  [key: string]: T;
}
const ctr: Container<T>;
ctr['stringKey']. // gives `T.` completions

const arr: T[];
arr[0]. // gives `T.` completions
```

Note that this does _not_ provide completions for properties indexed by
string literals, e.g.

```typescript
interface Container<T> {
  foo: T;
}
const ctr: Container<T>;
ctr['foo']. // does not give `T.` completions
```

Keen Yee Liau cbb1d9f2bb fix(compiler-cli): Refactor getTsTypeFromBuiltinType (#33778)
This commit fixes a few issues with helper method
`getBuiltInTypeFromTsType`.

1. The function is wrongly named. It should be the other way round.
2. The ts.Type returned by the function should not contain any value.
This is because for some data types like Number and String, the
SourceFile (context.node) is not the correct value. Value is never
needed for program correctness in this case.

Keen Yee Liau c5a75fd807 fix(language-service): Recompute analyzed modules only when source files change (#33806)
This commit fixes a bug brought up by @andrius-pra whereby the language
service host would recompute the analyzed modules even when none of the
source files changes. This is due to a bug in our unit test that
precludes non-TS files from incrementing the project version.
Consequently, when the external template is updated, the program remains
the same.

With the bug fixed, the next step is to figure out if any source files
have been added / changed / removed since the last computation. The
previously analyzed could be safely retained only when none of these
operations happen.

Greg Magolan 1c22e464b2 build: remove deps on legacy nodejs rules rollup_bundle internals (#33201) (#33607)
The legacy nodejs rules rollup_bundle is now deprecated and will be removed in the nodejs rules 1.0 release due in mid-November. This PR brings in the rules_nodejs internal API deps that ng_rollup_bundle, ng_package and ls_rollup_bundle depend on into this repo to break the dependency. In the future these rules should switch to use the new rollup_bundle via a macro as done in https://github.com/angular/angular/pull/33329 but this is not possible right now due to the complication of having esm5 re-rooted ts_library dependencies.

The es6 sources now have .mjs extensions so they no longer need to be re-rooted to `{package}.es6`. This eliminates the need for the collect_es6_sources() function.

Note: repo has been updated to the newest working version of rollup which is 1.25.2. There is some regression in 1.26.0 which causes the following bundling failure:

ayazhafiz ee4fc12e42 refactor(language-service): find expression ASTs using absolute spans (#33387)
Moves to using the absolute span of an expression AST (relative to an
entire template) rather than a relative span (relative to the start
of the expression) to find an expression AST given a position in a
template.

This is part of the changes needed to support text replacement in
templates (#33091).

Keen Yee Liau 73530a9e25 refactor(language-service): Create ng.CompletionEntry to replace ts.CompletionEntry (#33379)
It is messy to keep casting `CompletionEntry.kind` from
`ng.CompletionKind` to `ts.ScriptElementKind`.

Instead, create a new type `ng.CompletionEntry` that is exactly the same
as `ts.CompletionEntry`, but with the `kind` type overridden to
`ng.CompletionKind`.

This way, we only have to cast it once, and can do so in a safe manner.

Keen Yee Liau 65a0d2b53d fix(language-service): Preserve CRLF in templates for language-service (#33241)
This is a potential fix for https://github.com/angular/vscode-ng-language-service/issues/235
suggested by @andrius-pra in
47696136e3.

Currently, CRLF line endings are converted to LFs and this causes the
diagnostics span to be off in templates that use CRLF. The line endings
must be preserved in order to maintain correct span offset. The solution
is to add an option to the Tokenizer to indicate such preservation.

Keen Yee Liau 11bf7679a1 fix(language-service): reset MockHost after every spec instead of creating new LS (#33200)
This commit speeds up the tests by calling `MockHost.reset()` in
`beforeEach()` instead of destroying the entire language service and
creating a new one. The creation of a new language service instance is
expensive due to the need to initialize many core Symbols when creating
a new program.

This speeds ups the test (on my local machine) from 35 secs to 15 secs.

There are many specs in `ts_plugin_spec.ts` that exercise the behavior
of completions. These specs should belong in `completions_spec` instead.

In addition,

ayazhafiz ce7f934c66 feat(language-service): directive info when looking up attribute's symbol (#33127)
Now, hovering over an attribute on an element will provide information
about the directive that attribute matches in the element, if any.
(More generally, we return information about directive symbols
matched on an element attribute.)

I believe this is similar to how the indexer provides this kind of
information, though more precise in the sense that this commit provides
directive information only if the directive selector exactly matches the
attribute selector. In another sense, this is a limitation.

In fact, there are the limitations of:

- Directives matched on the element, but with a selector of anything
  more than the attribute (e.g. `div[string-model]` or
  `[string-model][other-attr]`) will not be returned as symbols matching
  on the attribute.
- Only one symbol can be returned currently. If the attribute matches
  multiple directives, only one directive symbol will be returned.
  Furthermore, we cannot say that the directive symbol returned is
  determinstic.

Resolution of these limitations can be discussed in the future. At least
the second limitation should be very easy to fixup in a future commit.

This relies solely on the template compiler and is agnostic to any Ivy
changes, so this is strictly a feature enhancement that will not have to
be refactored when we migrate the language service to Ivy.

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
