build: Rework data files

GResource entries are split into two files:
- `bottles.gresource.xml` remains the GResource file for UI
  files and CSS, with everything else removed.
- `data.gresource.xml` is being introduced for anything related
  to data, such as icons, and in the future
  `Adw.AboutDialog.new_from_appdata ()`.

Most unneeded icons, for instance `data/icons/*/48`, have been
removed. They served no purpose whatsoever, so there's no
point in keeping them.

Every XML-like file runs through a preprocessor to make them
take less space.
