Tobias Bosch 957be960d2 fix(compiler): recover from structural errors in watch mode (#19953)
This also changes the compiler so that we throw less often
on structural changes and produce a meaningful state
in the `ng.Program` in case of errors.

Tobias Bosch 745b59f49c perf(compiler): only emit changed files for incremental compilation
For now, we always create all generated files, but diff them
before we pass them to TypeScript.

For the user files, we compare the programs and only emit changed
TypeScript files.

This also adds more diagnostic messages if the `—diagnostics` flag
is passed to the command line.

Tobias Bosch 6665d76fbb perf(compiler): speed up watch mode (#19275)
- don’t regenerate code for .d.ts files when
  an oldProgram is passed to `createProgram`
- cache `fileExists` / `getSourceFile` / `readFile` in watch mode
- refactor tests to share common code in `test_support`
- support `—diagnostic` command line to print total time
  used per watch mode compilation.
