Nathan Shively-Sanders 6ca9d04b60 Constructor functions as classes (#32944) 
* Initial implementation

The original test passes but I haven't run any other tests yet, so I
assume the world is now broken.

* Append constructor function construct sigs

Instead of overwriting them

* Grab bag of improvements.

1. Mark @class-tagged functions with Class too.
2. Only gather local type parameters of constructor functions.
3. Remove getJSClassType calls with getDeclaredTypeOfSymbol.
4. Add a couple more failing tests.

getDeclaredTypeOfClassOrInterface now needs to understand prototype
assignment. That's next, I think.

* Prototype assignments work now

1. Binder marks prototype assignments as Class now.
2. Checker merges prototype assignments using the same merge code as for
functions and their declarations. No more intersections.

Many fewer failing tests now.

* Mark prototype-property assignments as Class

Even if there are no this-property assignments in them. (Then why are
you using a class?).

* Simplify getJSClassType, remove calls to its guts

It's probably not needed because now it's just a conditional call to
getDeclaredTypeOfSymbol, and I think most callers already know whether
they have a JS constructor function beforehand.

* isJSDocConstructor doesn't need to check prototype anymore

Because all the properties are merged during getDeclaredTypeOfSymbol.

* outer type parameter lookup follow prototype assignment

* this-type and -expression support in ctor funcs

Pretty cool!

* Fix remaining tests

* Fix minor lint

* Delete now-unused code

* Add class flag to nested class declarations

Also remove old TODOs
