153af03b94 gallium: Add cap to request state validation for all dirty state 
With aaa4b0e6 state validation is no longer called for all changed states,
but only for states that will be active with a new shader program.
Not all drivers support this and might prefer if the state validation
is emitted for all states that might be changed. So add a cap that the
driver can signal one or the other preference, and default to the new
behavior.

Fixes: aaa4b0e6
   st/mesa: move check_program_state code into _mesa_update_state

v2: - Rename cap and and invert its meaning, query the cap
      only once and store it in st, handle the mask update
      when updating the shader i.e. not in st_validate_state (Marek)

e3e74a4402 docs: move note on other drivers to the bottom 
This was always meant to be at the bottom of the page. To reduce the
risk of more driver-specific environment variables being added below,
let's add a horizontal rule to mark the difference. This should make it
more clear that this paragraph doesn't belong to the previous heading.

cd22bf90e7 ac/nir/ngg: refine nogs outputs handling 
Gather outputs in advance to save both output data and type. Output data
is used for streamout and gfx11 param export. Output type is used for
streamout latter.

The output info will also be used for nir vertex export in the future.

2976548e4a nir/gather_info: Handle store_zs_agx 
This acts as a depth/stencil write. The AGX compiler checks outputs_written to
determine what conservative depth settings the driver needs. Nominally, this
should work: the original store_output(FRAG_RESULT_DEPTH) intrinsic causes the
DEPTH outputs_written bit to be set, so the metadata is still correct after
lowering store_output to store_zs_agx. However, there are a handful of places
that call nir_gather_info late, which *resets* the existing outputs_written
value and regathers, causing Asahi to use the wrong conservative depth settings
when shuffling NIR pass order and breaking gl_FragDepth.

To fix, handle store_zs_agx conservatively when gathering info so we don't have
to play games with the pass order or stashing info in a sideband.

1b8bed38eb freedreno/a6xx: Remove shader key from fd6_emit 
Only construct the key on-demand if the PROG state is dirty.  The newly
added "virtual" PROG_KEY state is used to know when other state that the
shader key depends on changes.  Worth ~13% at drawoverhead test 0.

7b734cc668 freedreno/a6xx: Avoid zero-init fd6_emit 
A pretty significant amount of time spent in fd6_draw_vbo is calling
memset to zero init the on-stack struct.  And a big part of the size
of the struct is fd6_state, of which we only need to initialize
num_groups to zero.  This is worth a 15% improvement in drawoverhead
test 0 ("no state change").
