Fall back to "python" when "python3" is unavailable
On Windows with Anaconda/Miniforge, only "python" is available, not
"python3". After loading, check if "python3" can be found and, if
not, set the executable for all Python-based checkers to "python".
Users can still override individual checker executables via their
respective flycheck-<checker>-executable variables.
Closes #2062
