  grass.script: Add locking to init (#5591)

The function _gs.setup.init_ can now optionally lock the mapset and unlock when exiting the context or with call to finish (both free function or bound method). This keeps the current state of not locking as a default, i.e., the locking is opt-in, so multiple session are responsibility of the user just like running multiple processes within one mapset.

The PID used is the the current process ID which is already used for variable GIS_LOCK in init. The underlying locking (but not unlocking) functionality is the same one as used for the main _grass_ command thanks to a previous refactoring of locking from lib/init/grass.py to _grass.app.data_.
