Chuck Jazdzewski 01dd7dde24 chore(tools): Remove use of TypeChecker from metadata collector. 
The metadata collector was modified to look up references in the
import list instead of resolving the symbol using the TypeChecker
making the use of the TypeChecker vestigial. This change removes
all uses of the TypeChecker.

Modified the schema to be able to record global and local (non-module
specific references).

Added error messages to the schema and errors are recorded in
the metadata file allowing the static reflector to throw errors
if an unsupported construct is referenced by metadata.

Closes #8966
Fixes #8893
Fixes #8894

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 2 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.
