serverComponentsInlinedTransformStream is always null so TypeScript complained about unreachable code since serverComponentsInlinedTransformStream?.readable is equivalent to undefined.

test/tsconfig.json

After reading #59776, it seems like the root issue was resolve with #64117

The root tsconfig already includes the test files so it's unclear what the point of this project is.

packages/next/types/$$compiled.internal.d.ts

TypeScript didn't care to reference misc.d.ts in reachable declaration files for some reason. Now it does so we have two options:

Force the old behavior by not referencing misc.d.ts at all

Get rid of the two-world type-checking where internally we emit declarations with misc.d.ts but then publicly rely on compiled.d.ts existing in the program

Point 2 is quite involved since it requires having either the same types for internal and public or at least public types that are compatible with internal types. Right now, the public types are not compatible with the internal types (e.g. you can't redeclare a value even though its type is any). We'd have to inline Webpack types which is quite involved (mostly because there's no tool to bundle types, see microsoft/TypeScript#4433).

In this PR I choose 1. by rewriting references to $$compiled.internal.d.ts (the old misc.d.ts) to compiled.d.ts. This has the benefit of more clearly communicating what misc.d.ts and compiled.d.ts actually represented.

That the rewrite is sound (or at least as sound as prior typings were) is ensured by the new typechecking tests from #64478 and all the existing tests including type-checking.

packages/next/types.js

This is just a new safety measure in case somebody imports from next/types without a type modifier. Such an import may not be elided by during transform which may result in bundler errors because next/types.js doesn't exist.

packages/next/types/webpack.d.ts

Moved into packages/next/types/$$compiled.internal.d.ts

Fixes error TS2339: Property 'error' does not exist on type 'SafeParseReturnType<NextConfig, NextConfig>'. Property 'error' does not exist on type 'SafeParseSuccess<NextConfig>'. 1021 const [errorMessages, shouldExit] = normalizeZodErrors(state.error)

Combines misc.d.ts and webpack.d.ts into `$$compiled.internal.d.ts`. `$$compiled.internal.d.ts` represents type declarations necessary to type the implementation while `compiled.d.ts` represents declarations necessary to type the emitted declarations. This internal/public split is really just a typechecking perf improvement. We should just be able to include both public and internal ambient declarations in the declaratione emit program and then just test the internal one isn't referenced.

Removes a bunch of `@ts-ignore` and is more in line with our existing entrypoints. Required to entangle the public/internal types plit

5x more imports of dist than src Importing from src doesn't typecheck.

Is this a public api that we are going to break? I dont know if next/types is something the user would expect to import from.

Should be the same content. next/types used to resolve to next/types/index.d.ts. Now it resolves to next/types.d.ts which just reexports next/dist/types.d.ts. And since I just moved everything from next/types/index.d.ts into next/src/types.ts, the content should also be the same.

It's really just reorganizing files so that the program using the root tsconfig doesn't include Next.js source files.
