GHash: BLI_ghash_ensure_p_ex now takes a pointer-to-key arg

This is an alternative to passing a copy callback which is some times inconvenient.
Instead the caller can write to the key - needed when the key is duplicated memory.

Allows for minor optimization in ghash/gset use.

Also add BLI_gset_ensure_p_ex
