Chuck Jazdzewski c9f8718d2a fix(tsc-wrapped): don't rewrite imports when annotating for closure (#19579 )

Port of f24ea59f74552113f8e8586d2d69045254512aa to 4.4.x

Closure no longer needs to have the imports rewritten so avoid
rewriting as this can cause issues when the source directory
structure differs from what is deployed.

Fixes: #17171

tsc-wrapped

This package is an internal dependency used by @angular/compiler-cli. Please use that instead.

This is a wrapper around TypeScript's tsc program that allows us to hook in extra extensions. TypeScript will eventually have an extensibility model for arbitrary extensions. We don't want to constrain their design with baggage from a legacy implementation, so this wrapper only supports specific extensions developed by the Angular team:

tsickle down-levels Decorators into Annotations so they can be tree-shaken
tsickle can also optionally produce Closure Compiler-friendly code
./collector.ts emits an extra .metadata.json file for every .d.ts file written, which retains metadata about decorators that is lost in the TS emit
@angular/compiler-cli extends this library to additionally generate template code

TypeScript Decorator metadata collector

The .d.ts format does not preserve information about the Decorators applied to symbols. Some tools, such as Angular template compiler, need access to statically analyzable information about Decorators, so this library allows programs to produce a foo.metadata.json to accompany a foo.d.ts file, and preserves the information that was lost in the declaration emit.
