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.

* add test from #38551

* we ❤️ semicolons

In JS, assignment to void 0 isn't a declaration (#39452)
Previously, property assignments with `void 0` initialisers were treated
like any other values. But this causes us to choke when checking our own
commonjs emit. This is something that happens by mistake a fair amount,
so this PR goes back to treating these assignments as normal
assignments.

This should allow us to check our own emit in loose cases without
harming other code bases, since `void 0` is rarely written by hand.

Note that other errors still happen: noImplicitAny forbids
accessing undeclared properties on object literals, and strictNullChecks
forbids assigning `undefined` to properties with a different type.
However, this change is enough to unblock compilation with
`strictNullChecks: false`.

Node-based @deprecated checks (#39323)
* Node-based @deprecated checks

Switch the checker to syntactic checks for `@deprecated` on
declarations. This requires a bit more checking of declarations in the
checker at times, but it

1. Gets rid of work, and a symbol flag, in the binder.
2. Skips work in the checker unless there is a `@deprecated` tag.
3. Makes it fairly simple to only issue errors on particular signatures
   of overloaded functions.

* remove in-progress comment

* remove unused isTypeDeclaration

* ❤️ lint

* support jsx and tagged template functions

* Support decorators too

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.

Add missing index.ts files to user projects (#39163)

part of the parent project, so that you can view the same errors in the
editor as you see in the baselines.
