gtk/gtkcssrgbavalue.c: Fix build on Visual Studio
Hi,
From the commit message:
Visual Studio does not allow static or global variables to use non-constants in their aggregate initializers, so fix the build by doing such initializations as local and non-static initializations, which means some unavoidable duplication.
It seems that the current code in this file inadvertently made use of something outside of C99 in this case, from [1] and [2].

Visual Studio does not allow static or global structures to use static storage duration by compound literals, which is actually a GCCism[1].

With blessings, thank you!
