refactor(@angular/build): move compiler-cli loading to TypeScriptCompilation - #33979

…ilation AngularCompilation serves as the top-level compilation contract used across the build pipeline, including on the main thread via ParallelCompilation. Neither AngularCompilation nor ParallelCompilation requires loading @angular/compiler-cli or reading tsconfig.json configurations. The loadCompilerCli and loadConfiguration methods are now moved to TypeScriptCompilation, which is the base class for in-process TypeScript compilations (AotCompilation and JitCompilation). This completely decouples AngularCompilation from @angular/compiler-cli and ensures that compiler-cli loading and configuration parsing are localized exclusively to the worker compilation hierarchy.

Code Review
This pull request refactors the Angular compilation context by introducing an abstract AngularCompilationContext with concrete PrimaryCompilationContext and SecondaryCompilationContext implementations, replacing the previous NoopCompilation approach. This enables secondary compilation contexts to delegate readiness and compiler options to the primary context. Additionally, the loading of @angular/compiler-cli has been moved from AngularCompilation to TypeScriptCompilation. I have no feedback to provide as there are no review comments.
