Video textures do not work with bindless textures

[slipher]

videomap does not work when bindless textures are enabled. This is not a regression; they never worked together.

There's a test map for video textures https://users.unvanquished.net/~slipher/map-test-video_2.1-20231113-084535-c164c77.dpk

Moving the issue out of the project since it's the case with or without material system.
