src: remove fast API for InternalModuleStat

Browse Source 
There are several motivation for removing this:

1. The implementation does not align with InternalModuleStat,
   most noticably it does not namespace the path or convert
   it to UTF-16 before using it with std::filesystem::path
   on Windows which could crash on non-English locale.
2. It needs the Environment - if not for decoding the string,
   at least for env->exec_path() to resolve the path for
   namespacing - and therefore needs a handle to the Context
   which requires a handle scope which actually makes the
   fast API version slower than the normal binding.

For simplicity this just removes the fast API to fix the bug and
improve the performance.
