Subject: [PATCH] fix(@angular/build): disable TypeScript `composite` option
 with Angular compiler

The Angular compiler does not directly support the `composite` option within
a referenced `tsconfig` file. If this option is enabled, the Angular compiler
will crash due to the Angular compiler not leveraging the TypeScript
BuilderProgram infrastructure. Since the Angular compiler is not aware of
composite projects nor project references, the `composite` option is disabled
when options are passed to the Angular compiler. This has no effect on non-
Angular related usages of the `tsconfig`.
