Define a standard pkgconfig variable to store the g-i name for a library

Description
We need to have a bijunction between pkgconfig and g-i gir|typelib for a library. The gir format already defines a tag to link to the pkgconfig file. We would need a pkgconfig variable to have the other way of the relationship.
I would propose "gi-module:" but that may be another variable name.
