Fix T65914: Workbench Transparency Film

When performing F12 render on a transparent film all solid objects where
a bit transparent. Single Pass AA and no AA passes were not visible at
all.

Issue was that the first frame was not handled correctly making these
artifacts. This commit changes the order of `GPU_state_init` and
`DRW_state_reset` so the state is correct during the first pass.
