Implement automatic precompilation - horst3180#656 Following the path…

… of Adwaita, this commit implements the automation to automatically precompile the GTK3 theme versions to gresource binary files, to improve performance of theme rendering, and avoid unnecessary re-read and re-parsing of the theme on every app run. . Given that the theme is coded in sass to begin with directly altering it is not a reasonable thing to do, and so we don't loose anything by having the installed theme in binary form, specially when accessing the sources is easy enough. . The takes horst3180#656 and adds to this proposed commit and ensures that precompilation works for both GTK+3.18 and later GTK+ versions
