gir: GValue parameters carrying types are now inout (#638)
Regularize gir annotations on GValue parameters:
- (out caller-allocates) marks GValue parameters that must not be initialized before calling the function
- (inout) marks GValue parameters that must be initialized before calling the function. These parameters must be initialized with a specific type, except where noted.

Fixes #638.
@slomo I added (transfer none) where I thought it made sense, based on #638 (comment 725993) . Let me know what you think!
Thanks for considering this MR!
