rhi: Drop the zeroing out of resource binding structs

This has a non-insignificant cost (since the size is at least 260 bytes)
in renderers that construct a lot of these objects per frame. After
changing the qHash implementation to be lighter we no longer rely on
qHashBits, so zeroing it is not essential anymore. Remove it.
