IDL build: factor out global objects action into a GYP template

IDL build: factor out global objects action into a GYP template

First (simple) step in factoring out redundant GYP actions into templates.
Also moves the 'write_file_only_if_changed' flag to scripts, as that's where
it's used, which allows more simplification.
