Fix duplicate identifier error with module.exports (#24466)
A bug in checkSpecialAssignment added bogus duplicate identifier errors
when using module.exports assignment to export a class. This commit
fixes that.

Skip IntrinsicAttributes elaboration in JSX errors (#24461)
* Skip IntrinsicAttributes elaboration in JSX errors

Do not issue an error message for a source type that comes from JSX
attributes and a target type that is an intersection containing
IntrinsicAttributes or IntrinsicClassAttributes. This will make error
messages simpler and less confusing.

Note:
1. There will always be elaboration under the skipped message, so this
won't elide errors completely.
2. Rarely (once in the tests) the intersection type will have more that
one non-Intrinsic* member. However, these additional members don't
provide useful information either, so it's fine to skip them.

* Add test of IntrinsicAttributes error

* Fix indentation in test

Fix jsdoc type resolution [merge to master] (#24204)
* Fix JSDoc type resolution

Breaks type parameter resolution that is looked up through prototype
methods, though. I need to fix that still.

* Check for prototype method assignments first

* Undo dedupe changes to getJSDocTags

* JS Type aliases can't refer to host type params

Previously, js type aliases (@typedef and @callback) could refer to
type paremeters defined in @template tags in a *different* jsdoc tag, as
long as both tags were hosted on the same signature.

* Reduce dedupe changes+update baseline

The only reason I had undone them was to merge successfully with an
older state of master.

Add callback tag, with type parameters (#23947)
* Add initial tests

* Add types

* Half of parsing (builds but does not pass tests)

* Parsing done; types are uglier; doesn't crash but doesn't pass

* Bind callback tag

Builds but tests still don't pass

* Only bind param tags inside callback tags

* Fix binding switch to only handle param tags once

* Checking is 1/3 done or so.

Now I'm going to go rename some members to be more uniform. I hate
unnnecessary conditionals.

* Rename typeExpression to type (for some jsdoc)

(maybe I'll rename more later)

* Rename the rest of typeExpressions

Turns out there is a constraint in services such that they all need to
be named the same.

* Few more checker changes

* Revert "Rename the rest of typeExpressions"

This reverts commit f41a96b24d44a6b696d39eee9e91ef7f606bea52.

* Revert "Rename typeExpression to type (for some jsdoc)"

This reverts commit 7d2233a00e5c6d794c1de32c03802e8ccce1914c.

* Finish undoing typeExpression rename

* Rename and improve getTypeParametersForAliasSymbol

Plus some other small fixes

* Core checking works, but is flabbergastingly messy

I'm serious.

* Callback return types work now

* Fix crash in services

* Make github diff smaller

* Try to make github diff even smaller

* Fix rename for callback tag

* Fix nav bar for callback tag

Also clean up some now-redundant code there to find the name of typedefs.

* Handle ooorder callback tags

Also get rid of redundant typedef name code *in the binder*. It's
everywhere!

* Add ooorder callback tag test

* Parse comments for typedef/callback+display param comments

* Always export callbacks

This requires almost no new code since it is basically the same as
typedefs

* Update baselines

* Fix support for nested namespaced callbacks

And add test

* Callbacks support type parameters

1. Haven't run it with all tests
2. Haven't tested typedef tags yet
3. Still allows shared symbols when on function or class declarations.

* Template tags are now bound correctly

* Test oorder template tags

It works.

* Parser cleanup

* Cleanup types and utilities

As much as possible, and not as much as I would like.

* Handle callback more often in services

* Cleanup of binder and checker

* More checker cleanup

* Remove TODOs and one more cleanup

* Support parameter-less callback tags

* Remove extra bind call on template type parameters

* Bind template tag containers

Doesn't quite work with typedefs, but that's because it's now stricter,
without the typedef fixes. I'm going to merge with jsdoc/callback and
see how it goes.

* Fix fourslash failures

* Stop pre-binding js type aliases

Next up, stop pre-binding js type parameters

* Further cleanup of delayed js type alias binding

* Stop prebinding template tags too

This gets rid of prebinding entirely

* Remove TODO

* Fix lint

* Finish merge with use-jsdoc-aliases

* Update callback tag baselines

* Rename getTypeParametersForAliasSymbol

The real fix is *probably* to rename Type.aliasTypeArguments to
aliasTypeParameters, but I want to make sure and then put it in a
separate PR.

Fix stack overflow in merge symbol (#24134)
* JS initializers use original valueDecl, not mutated

target's valueDeclaration is set to the source's if it is not present.
This makes it incorrect to use getJSInitializerSymbol because it relies
on the symbol's valueDeclaration.

This fix just saves the original valueDeclaration before mutating and
uses that.

* Compare merged targetInitializer to target

Instead of the unmerged one

* Add test of stack overflow
