* Also enhanced reporting error exit reporting through the scons logger to provide
the exception in the compilation report.
* More error exits in scons should do this.
* This allows to avoid a useless file copy to a temporary file
in case a "importlib.resources.path" is used.
* Also fixed a few typos in tests.
* And avoid compiling the meta path based loader separately, so it
can use compiled code helpers easily.
