This fixes all our GObject Introspection issues with GimpUnit which was both an enum and an int-derived type of user-defined units *completing* the enum values. GIR clearly didn't like this! Now GimpUnit is a proper class and units are unique objects, allowing to compare them with an identity test (i.e. `unit == gimp_unit_pixel ()` tells us if unit is the pixel unit or not), which makes it easy to use, just like with int, yet adding also methods, making for nicer introspected API. As an aside, this also fixes #10738, by having all the built-in units retrievable even if libgimpbase had not been properly initialized with gimp_base_init(). I haven't checked in details how GIR works to introspect, but it looks like it loads the library to inspect and runs functions, hence triggering some CRITICALS because virtual methods (supposed to be initialized with gimp_base_init() run by libgimp) are not set. This new code won't trigger any critical because the vtable method are now not necessary, at least for all built-in units. Note that GimpUnit is still in libgimpbase. It could have been moved to libgimp in order to avoid any virtual method table (since we need to keep core and libgimp side's units in sync, PDB is required), but too many libgimpwidgets widgets were already using GimpUnit. And technically most of GimpUnit logic doesn't require PDB (only the creation/sync part). This is one of the reasons why user-created GimpUnit list is handled and stored differently from other types of objects. Globally this simplifies the code a lot too and we don't need separate implementations of various utils for core and libgimp, which means less prone to errors.
