This was a bad idea because:
- it diverges too much with the fragment shader epilog
- it doesn't allow to implement alpha-to-coverage via MRTZ correctly
- it was supposed to be used by LLVM but this never happened
Reverting this back allows us to fix alpha-to-coverage via MRTZ
on GFX11 easily, including for fragment shader epilogs.

16-bit isn't possible. Note that this is currently style broken for
compressed formats because the w channel is never written to.

Such cursed behavior is almost non existent in practise. When capturing
a Doom Eternal, this warning spams the output for no reason.
The warning is also unnecessary since we copy acceleration structures
right after building them now.

Since we have ZRAM now, we can enable previously failing tests on OOM.

Looking at VOPD things, shifts are not very likely to get dual issued
but plain moves are. Looking at RDNA2 v_lshrrev_b64 are half the perf
of v_mov_b32 (but you need twice as many moves), so on GFX11 this likely
reaches the threshold where moves are faster.

Before this commit each stream will emit a query block, now

LDS will be accessed starting from esgs_ring which has offset 0.
So ngg_scratch and ngg_emit base address is just the offset from
the esgs_ring base.
