[PATCH v3 1/4] BaseTools: Remove Python2/Python3 detection from toolset.bat

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

Since Python3 is now required, we can remove the checks for PYTHON3_ENABLE
and PYTHON3 and simplify the code in toolsetup.bat. Also, remove the
leftover from when we supported freezing Python code.

While here, fix a couple of typos and improve error messages.
