b0450aed56 Add codefix for --noImplicitThis (#27565)
* Add codefix for --noImplicitThis

* Code review

* Back to building post-merge

* Remove redundant functions + update tests

Infer-from-usage also inserts `this: any` parameters when needed, so I
removed that from fixImplicitThis.

Otherwise, fixImplicitThis has better suggestions than inferFromUsage,
so I moved inferFromUsage later in the suggestion order.

* More redundancy removal

Don't need to add `@this` anymore either since inferFromUsage will do
that.

* More baseline updates

From moving inferFromUsage down in priority I think?

* remove now-redundant ad-hoc jsdoc emit

* fix more bad merge

9e97b00ca1 adds error message for using value as type argument (#37359)
This addresses issue #28975
(https://github.com/microsoft/TypeScript/issues/28975).

When providing a value as a type argument, we can suggest a more specific
error message: "Did you mean to use typeof T?"

adds error message

WIP: Detect error

WIP: progress

updated tests

janky implementation

adds test coverage around literal types being unaffected

refactor out isIdentifierATypeArgument function

adds test case for type alias

adds test case for nested type arguments

fixes linting errors

merge master into branch to overwrite changes

changes value as type error message

This suggests 'typeof T' as a potential alternative when we give an error
about using value T as a type.

remove stale tests from old change

ffde92349d Added @ts-expect-error to @ts-ignore directives (#36014)
* Added @ts-expect-error to @ts-ignore directives

Similar to `// @ts-ignore`, but will itself cause a new error diagnostic if it does not cause an existing diagnostic to be ignored.

Technical summary:
1. The scanner will now keep track of `CommentDirective`s it comes across: both `@ts-expect-error` and `@ts-ignore`
2. During type checking, the program will turn those directives into a map keying them by line number
3. For each diagnostic, if it's preceded by a directive, that directive is marked as "used"
4. All `@ts-expect-error` directives not marked as used generate a new diagnostic error

* Renamed to getDiagnosticsWithPrecedingDirectives per suggestion

* Added JSDoc comment I thought I did already
