fix(compiler-cli): do not add references to files outside of rootDir (#19770)

References to resources (such as .css files) that are generated into
the `outDir` directory outside of `rootDir` would cause a spurious
compiler error about not being able to find a files that ends in
'.ngstyle.ts'.

Also fixed a minor issue in compiler error reporting
