[oe] [PATCH 2/2] gnome-desktop3: rework gobject-introspection handling

[Andreas Müller]

gobject-introspection is mandatory for gnome-desktop3 - there is no configure
option to enable or disable it.

To handle properly, this patch does:

* Make 'gobject-introspection-data' a required distro feature
* To avoid trouble once pending patch removing
'UNKNOWN_CONFIGURE_WHITELIST_append = " --enable-introspection --disable-introspection"'
are in oe-core [1] - set in recipe to avoid
| ERROR: gnome-desktop3-3.32.0-r0 do_configure: QA Issue: gnome-desktop3: configure was passed unrecognised options: introspection [unknown-configure-option]

This does not handle MACHINE_FEATURES / qemu-usermode case but there other
issues of higher priority.
