freedreno/ir3: moar better scheduler

Add a new pass that inserts additional dependencies, rather than simply
relying on SSA srcs added in the nir->ir3 frontend.  This makes it
easier to deal with barriers, but the additional false deps also lets us
deal properly with ensuring a write depends on all previous reads.

Since conversion to barrier instructions is lossy (ie. just knowing the
instruction doesn't tell us enough about what other instructions the
barrier applies to), use barrier_class/barrier_conflict fields in the
ir3_instruction to retain this information.

This could probably be relaxed somewhat by considering *which* array/
buffer/image variable is being referenced.  Ie. a write to buffer A
can overtake a read from buffer B, if B is not coherent.  (right?)

freedreno/ir3: move macros

I want to add a growable array to ir3_instruction, so we can append

dealing with write after read hazards.

swr: Fixed an uncommon freed-memory access during state validation

State validation is performed during clear and draw calls.  Validation
during clear was still accessing vertex buffer state.  When the currently
set vertex buffers are client arrays, this could lead to accessing freed
memory.  Such is the case with the VMD application.

Previously, vertex buffer validation depended on a dirty bit or the
draw info indicating an indexed draw.  This required special handling for
clears.  But, vertex buffer validation still occurred which was unnecessary
and wrong.

Now, only minimal validation is performed during clear, deferring the
remainder to the next draw.  And, by setting the dirty bit in swr_draw_vbo
for indexed draws, vertex buffer validation is only dependent upon a
single dirty bit.

This fixes a bug exposed by the VMD application when changing models.

anv: Better types for 'aspect' function params

Some functions have a comment that says "Exactly one bit must be in
'aspect'". So change the type of their 'aspect' parameter from
VkImageAspectFlags to VkImageAspectFlagBits.

gallium: add CAPs to support HW atomic counters. (v3)

This looks like an evergreen specific feature, but with atomic
counters AMD have hw specific counters they use instead of operating

I've left the CAP for atomic type extensible in case someone
else has a variant on this sort of thing (freedreno maybe?)

meson: Add script to use VERSION file for getting version

Meson has up until this point set it's version in the root meson.build
script, while the other build systems read the VERSION file. This is
just "one more thing" to duplicate between meson and every other build
system. This script is a simple "read, strip, print" sort of deal to

I chose to implement this in python since python is portable, and to
