fix(@angular/build): use rootDir for HMR component updates path resolution

Use `compilerOptions.rootDir` when calculating the relative path for HMR component updates, falling back to the current directory if not set. This ensures correct path resolution when `rootDir` is configured in `tsconfig`.

Closes #33005 and closes #32998
