Greg Magolan 0addaab270 build: remove deps on legacy nodejs rules rollup_bundle internals (#33201)
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:

Will leave that for another day.

Terser also updated to 4.3.3. Updating to 4.3.4 (https://github.com/terser/terser/blob/master/CHANGELOG.md) turns comments preservation on by default which increases the size of the //packages/core/test/bundling/todo:bundle.min.js in CI. After bazelbuild/rules_nodejs#1317 terser can be updated to the latest as passing —comments /a^/ to args can turn off all comments for the //packages/core/test/bundling/todo:bundle.min.js size test.

ayazhafiz da4eb91283 feat(language-service): add support for text replacement (#33091)
Adds a `replacementSpan` field on a completion that will allow typed
text to be replaced with the suggested completion value if a user
selects the completion. Previously, the completion value would simply be
appended to the text already typed. E.g. if we had

```
{{ti}}
```

typed in a template and `title` was recommended as a completion and
selected, the template would become

```
{{tititle}}
```

With `replacementSpan`, the original text `ti` will be replaced for
`title`.

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

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.
