meson: Provide our Python tools for builds

Browse Source 
Several of our tools are installed and are used by other projects to
generate code. However, there is no 'install' when projects use glib
as a subproject.

We need some way for glib to 'provide' these tools so that when some
project uses glib as a subproject, find_program('glib-mkenums') will
transparently return the glib-mkenums we just built.

Starting from Meson 0.46, this can be done with the
`meson.override_find_program()` function.

As a bonus, the Meson GNOME module will also use these
'overriden'/'provided' programs instead of looking for them in PATH.
