Validate that mapped buffers aren't used in submits.

Likewise "presented" textures won't be available for use in submits so
this sets up state-tracking and validation for textures too.

Command buffer resource usage is now stored in the frontend instead of
done per-backend because it is used to validate resources are allowed in
the submits.

Also adds a test.
