[Feature] Support Resolution of the Exact tsconfig File

[Char2sGu]

Currently @deepkit/type-compiler reads tsconfig.json only, ignoring the true tsconfig file used for execution or compilation, which might be tsconfig.build.ts or tsconfig.app.ts.

This behavior might force us to mess up the responsibility of each tsconfig file. It would be better to support resolution of the exact tsconfig file.

We do not have any information in TypeScript transformers about the build. It could be a tsc or a Project References build via tsc --build. Thus, there is no way to correctly determine which tsconfig is actually the correct one for a particular file.
