gl_common: add some sort of locking API
Some OpenGL implementations on some platforms require that a context
is current only on one thread. For this reason, mpgl_lock() and
mpgl_unlock() take care of this as well for convenience.
Each backend that needs thread safety should provide it's own locking strategy
inside of `set_current`.
