[glib2] Introspection files not generated

[jwharm]

Description / Steps to reproduce the issue

GObject-Introspection allows libraries to export their API in an xml repository (.gir) file. These files are installed under /usr/share/gir-1.0/ and are commonly used by language bindings.

In the past (until glib 2.78), the introspection outputs for glib, gobject, gmodule and gio were generated not from the glib2 package itself, but by building and installing a separate package, gobject-introspection. Since glib 2.80, this has been integrated into glib itself.

However, in the MINGW packages, the 'introspection' build option is still disabled for the glib2 package, so it doesn't generate and install the .gir files.

The mingw-w64-gobject-introspection package will still install the gir files, but those are the old ones for glib 2.78.

Steps to reproduce:

1. pacman -S mingw-w64-x86_64-glib2 --> installs glib 2.80
2. ls /mingw64/share/gir-1.0/GLib-2.0.gir --> does not exist
3. pacman -S mingw-w64-gobject-introspection
4. ls /mingw64/share/gir-1.0/GLib-2.0.gir --> file exists, but is based on glib 2.78

Expected behavior

GLib-2.0.gir, GObject-2.0.gir, GModule-2.0.gir and Gio-2.0.gir are generated when building mingw-w64-x86_64-glib2 and installed into /mingw64/share/gir-1.0/.

Actual behavior

The gir files are not installed with the glib2 package.

Are you willing to submit a PR?

Yes

Yes, this is expected. gobject-introspection has not been updated yet.
