meson: Declare GLIB_VERSION_* macros at configure

Browse Source 
So far we have three places where glib version is recorded:
meson.build and then in config.h. The latter is so well hidden
that it's easy to miss when bumping minimal glib version in the
former. With a bit of python^Wmeson string magic
GLIB_VERSION_MIN_REQUIRED and GLIB_VERSION_MAX_ALLOWED macros can
be defined to match glib_version from meson.build.
