[edk2-stable202305 PATCH 1/3] BaseTools: Update toolsetup.bat to not use BASETOOLS_PYTHON_SOURCE

["Rebecca Cran" <rebecca@bsdio.com>]

The BASETOOLS_PYTHON_SOURCE environment variable is only used temporarily to
set PYTHONPATH. Since it doesn't help improve clarity, remove it.

While here, make sure we set PYTHONPATH when we're using Pip BaseTools
so that build etc. can be found.
