d12116d8da Fix all internal JSDoc comments
If these are regular comments, then they won't appear in our d.ts files.
But, now we are relying on an external d.ts bundler to produce our final
merged, so they need to be present in the "input" d.ts files, meaning
they have to be JSDoc comments.

These comments only work today because all of our builds load their TS
files from scratch, so they see the actual source files and their
non-JSDoc comments.

The comments also need to be attached to a declaration, not floating,
otherwise they won't be used by api-extractor, so move them if needed.

07758c08ab Generated module conversion step - inlineImports
This step converts as many explicit accesses as possible in favor of direct imports from the modules in which things were declared. This restores the code (as much as possible) back to how it looked originally before the explicitify step, e.g. instead of "ts.Node" and "ts.Symbol", we have just "Node" and "Symbol".

b6c0538826 Generated module conversion step - stripNamespaces
This step converts each file into an exported module by hoisting the namespace bodies into the global scope and transferring internal markers down onto declarations as needed.

The namespaces are reconstructed as "barrel"-style modules, which are identical to the old namespace objects in structure. These reconstructed namespaces are then imported in the newly module-ified files, making existing expressions like "ts." valid.

9a0b85ce2a Generated module conversion step - explicitify
This step makes all implicit namespace accesses explicit, e.g. "Node" turns into "ts.Node".

94724a8c2e Generated module conversion step - unindent
This step makes further commits look clearer by unindenting all of the top level namespaces preemptively.

541e553163 Specific diagnostic suggestions for unexpected keyword or identifier (#43005)
Error message improvement for unexpected tokens in the following situations:

* A word was parsed that seems to have a low edit distance from a known common keyword
* A word was parsed that seems to be a known common keyword and a name _without_ a space in-between
* Parsing in a particular type of node (mostly a class property declaration) got a different word or token than expected

___

* Specific diagnostic suggestions for unexpected keywords or identifier

* Don't reach into there, that's not allowed

* Improved error when there is already an initializer

* Specific module error message for invalid template literal strings

* Skip 'unexpected keyword or identifier' diagnostics for declare nodes

* Improve error for function calls in type positions

* Switch class properties to old diagnostic

* Corrected errors in class members and reused existing textToKeywordObj map

* Corrected more baselines from the merge

* Update src/compiler/parser.ts

Co-authored-by: Daniel Rosenwasser <DanielRosenwasser@users.noreply.github.com>

* Mostly addressed feedback

* Clarified function call type message

* Split up and clarified parsing vs error functions

* Swap interface name complaints back, and skip new errors on unknown (invalid) tokens

* Used tokenToString, not a raw semicolon

* Inline getExpressionText helper

* Remove remarks in src/compiler/parser.ts

086423729a Add jsdoc member names: Class#method (#44150)
* Everything mostly works

A couple of mixed, nested references don't work yet.
The scanner+parser interaction is wrong, the parser consumes one too
many spaces, and the checker+services code needs a little cleanup.

* Cleanup

1. I decided that correctly parsing a#b.c, an entity name containing an
instance reference, is not worth the work.
2. I made the scanner, at least the jsdoc part, emit a # token, and
provided a reScanPrivateIdentifier in order to convert #a to # a.
3. I cleaned up the code in the checker.
2. Unrelated: I added a missing space in linkPart display.

* Cleanup lint + var naming

* investigate+clean up a couple of TODOs

* Fix lint in utilities.ts

* change name to JSDocMemberName

8ed251d0c7 Support xml namespace prefix for JSX elements and attributes (#37421)
* Support xml namespace prefix for JSX elements and attributes

Just as with the `-` character, `:` is now also treated specially in JSX
element and attribute names, but is only allowed a single time, and not
at the beginning or end of the name, as is specified in the JSX spec.
All tests in jsxInvalidEsprimaTestSuite still fail, but for slightly
different reasons now. Two lines in jsxEsprimaFbTestSuite were
uncommented as they included elements with namespaces, and they now pass
without error.

9a65658b28 Parse *= separately in types (#39457)
* Parse *= separately in types

Previously, when the scanner produced `*=` as a single token, the type
parser ran special-case code to produce an "optional all type", which
only makes sense when the `=` really should be attached to the `*`. This
is often not the case.

The correct solution, which I missed when I first wrote this code, is to
have the scanner go back and produce a separate `=` token, which is what
this PR does.

0f9d4c78d4 JSDoc uses same newlines as normal scanner (#39351)
* JSDoc uses same newlines as normal scanner

Previously, scanJsDocToken treated each newline character separately, so
the sequence \r\n would be treated as two lines. This is unexpected, and
not the way the normal scanner does it.

This change makes the jsdoc scanner behave the same as the normal
scanner.

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
