Jake Bailey db440d8468 Directly import namespaces for improved esbuild output
I should report this upstream, if I can manage to minimize this.

Jake Bailey c65142244c Add dts bundling
This adds a "small" d.ts bundler script. This script is very basic,
using Node printing to produce its output. Generally speaking, this is
inadvisable as it completely disregards name shadowing, globals, etc.
However, in our case, we don't care about the globals, and we can opt to
restructure our codebase in order to avoid conflict, which we largely
had to do anyway when we were namespaces and everything was in scope.

Jake Bailey 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.

Jake Bailey 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".

Jake Bailey 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.

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

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

Daniel Rosenwasser 76357ba802 Swap forEachChild to use a table of functions instead of a switch statement. (#50225)
* Swap `forEachChild` to use an array of functions instead of a `switch` statement.

* Let's see if 'new' changes anything.

* Co-locate each assignment into `forEachChildTable`.

* Try `push`ing undefined to create a packed Array.

* Try using an unconditional no-op function.

* `forEach` -> `forEachChildIn`

* Remove the optional chain if we are pre-filling with no-ops.

* Grab function directly to avoid possible `.call` overhead from downlevel emit.

* Swap to object literal.

* Lints and formatting.

Sheetal Nandi 394f51aeed Fix implied formats, file watching, new source file creating during edits (#50098)
* Add test where module resolution cache is not local and hence doesnt report errors in watch mode

* Ensure module resolution cache is passed through in watch mode

* Remove unnecessary setting of impliedFormat which should anyways be done as part of create source file

* Add test for packge.json changing and modifying implied format

* Distinguish between package.json watch and affecting file location watch

* Pass in failed lookup and affected file locations for source file's implied format
Also stop creating options if we already have them

* Add diagnostic for explaining file's implied format if based on package.json

* Watch implied format dependencies for modules and schedule update on change

* For program if implied node format doesnt match create new source file. Handle implied node format in document registry
Fixes #50086

* Modify tests to show package.json being watched irrespective of folder its in

* Check file path if it can be watched before watching package.json file

* Because we are watching package.json files and failed lookups its safe to invalidate package json entries instead of clearing them out everytime program is created

* Remove todos

* Fix the incorrect merge

* Pickup PackageJsonInfo renames from #50088

* Rename

Nathan Shively-Sanders 2a78b225d0 Stop tag after @callback from crashing (#48860)
By copying the kludge in @typedef. @callback's order is simpler, so the
kludge is simpler. However, it's wrong here, and in @typedef. Parsing
tag comments is normally supposed to happen at the end of a tag, but in
@callback and @typedef happens *before* parsing the nested
@param/@property tags.

I still need to figure out what a real fix is -- but for the beta,
copying the existing crash-avoidance kludge from @typedef is best
anyway. I added a test case for typedefs for future use as well.

Wesley Wigham d1fa945261 Add moduleDetection compiler flag to allow for changing how modules are parsed (#47495)
* Add moduleDetection compiler flag to allow for changing how modules are parsed

The default setting is 'auto', where JSX containing files under react-jsx and react-jsxdev are
always parsed as modules, and esm-format files under module: node12+ are always parsed as modules,
in addition to the 'legacy' detection mode's conditions for other files. (Declaration files are exempt from
these new conditions)

The 'legacy' mode preserves TS's behavior prior to the introduction of this flag - a file is
parsed as a module if it contains an import, export, or import.meta expression.

In addition, there is a 'force' mode that forces all non-declaration files to be parsed as modules.
(Declaration files are still only modules if they contain a top-level import or export.)

This technically breaks the parser API, but it's kinda-sorta backwards compatible so long
as you don't need the functionality associated with more recent compiler flags.

* Fix post-merge lint

* Rename function

* Update default value documentation

* PR feedback

* Fix lint and typo
