if the driver attemping to load is not zink and not software, then
attempt a zink fallback on failure
this conservatively handles the case of "only zink is built", though it
is going to be noticeably slower at startup than loading zink directly

Traces of GLES games that ANGLE has taken frequently have no-op stencil
writes, which ANGLE and Zink both pass straight through. Given that we
support dynamic stencil state updates via tu_CmdSetStencil*(), draw time
really is the time for deciding this state unfortunately.
Reuse the fancier stencil write enables check from "can we do early z?" in
"can we do LRZ?". This gets one set of draws in among_us to have LRZ, but
I don't see a detectable performance difference.

Change the terminology around the post-RA optimizer, primarily this
changes the use of "clobbered" to "overwritten" to avoid confusion,
and it removes some redundant states.
Proposed for backporting to stable, to make sure it is easy to
backport further fixes (if any) on top of this.

This assumption is no longer true since the post-RA optimizer

These are intended to make sure that the post-RA optimizer works
correctly across control flow. The new tests emit a divergent
if-else branch (with full logical+linear CFG).
- dpp_across_cf:
Simple case of DPP optimizable across control flow. Should pass.
- dpp_across_cf_overwritten:
Similar case but the DPP source register is overwritten in CF.
This shows a bug so the test fails now (will be fixed).

This commit adds an extra check on the emitted ppp state by
adding an EMIT_MASK.
The mask is just a copy of the header at the beginning of the emit.
Each time a word is emitted the appropriate bit in the mask is
cleared and at the end we make sure that the mask is 0. If not,
we forgot the either clear a bit somewhere or emit some words.
This is intended to make it easier to find such errors.

Previously `struct pvr_emit_state` was used to keep track of which
state update required emitting and the header was setup based on that.
This commit removes it so that we're instead setting up the header as
we go and we can emit it directly instead of decoding it based on the
emit_state (which is almost identical but with a few missing fields).
This commit also changes pvr_emit_ppp_state() so that each control
stream word is packed/emitted on its own instead of everything
being nested within the header pack. Making the code a bit easier
to follow.
