fix(compiler-cli): flatModuleIndex files not generated on windows with multiple input files (#27200) 

* Currently when building a `ng_module` with Bazel and having the flat module id option set, the flat module files are not being generated because `@angular/compiler-cli` does not properly determine the entry-point file.

Note that this logic is not necessarily specific to Bazel and the same problem can happen without Bazel if multiple TypeScript input files are specified while the `flatModuleIndex` option has been enabled.
