revert old mocking for bindless textures (#3331)

this revert is intended to bring back the original behavior (throw exception) for untracked bindless textures.
reason: this was a mock intended to extend ender magnolia's mean time to crash.
by reverting it we will be able to identify more games which rely on bindless textures, and avoid to obfuscate visual issues investigation on them.

this is super safe to merge. if any game that was benefitting of it gets visual regression, we will know immediately via the throw message in logs.
