GPU: Fix wrong state before python callbacks
This was caused by a missing state apply.
We force the GPUState to be set after the callbacks to avoid
desync between our state tracker and the real gl state.
This fixes some issues but a better general fix for all BGL would
be better.
This fix T80297 2.91 texture alpha is not transparent
