On Icelake and later, we can use a new 3DSTATE_BINDING_TABLE_POOL_ALLOC
command to update the location of the binder (buffer containing binding
table entries), rather than having to move Surface State Base Address
via a STATE_BASE_ADDRESS command. This has less stalling and also means
our surface addresses can remain relative to a fixed 4GB address range,
meaning we don't have to re-stream them any time the binder changes.

This workaround is needed on all Gfx12.0 parts, but doesn't appear to be
necessary on XeHP. The other drivers do not appear to be applying this
workaround on those parts. As further evidence, we accidentally added
the 3DSTATE_BINDING_TABLE_POOL_ALLOC commands after switching back to
GPGPU mode, which would be an incorrect way to implement the workaround,
and things seem to be working.

On Gfx11+, we're going to stop changing Surface State Base Address
and instead start changing the Binding Table Pool address instead.
So, rename a few things to track the last binder address, which is
what we're actually changing, regardless of how we program it.

Skylake and older use a 15:5 binding table pointer format, which means
our binder can be at most 64kB in size. Each binding table within the
binder must be aligned to 32B.
XeHP uses a new 20:5 binding table format, which allows us to increase
the binder size to 1MB while retaining the nice 32B alignment. Larger
binders mean fewer stalls as we update the base address for the binder.
Icelake and Tigerlake can either use the 15:5 format or an 18:8 format.
18:8 mode requires the base of each binding table to be aligned to 256B
instead of 32B, but it gives us a maximum binder size of 512kB.
We can store 64 binding table entries in a 256B chunk (256B / 4B = 64),
but only 8 entries in a 32B chunk (32B / 4B = 8). Assuming that most
binding tables have fewer than 64 entries, this means that with the 18:8
format, we're likely to be able to fit 2048 (512KB / 256B) tables into a
a buffer before needing to allocate a new one and stall.
Technically, the old format could also store 2048 binding tables per
buffer as well (64KB / 32B = 2048). However, tables that needed more
than 8 entries would need multiple 32B chunks. A single table would
take multiple aligned chunks, while with the larger 256B format, it
could fit in a single one.
This cuts binder resets by 6.3% on a Shadow of Mordor benchmark trace.

The idea of storing offsets in a separate UBO and lowering accesses to
UBOs/SSBOs with a dynamic offset was not great. Let's apply the offset
at UBO/SSBO emission time instead.

this comes in two flavors:
* streamout of array<struct/block>
* partial streamout of array/struct/block
for the former:
* arrays of structs can just be blasted out in the initial var declaration (easy)
* arrays of blocks must be output to separate xfb buffers for each array block,
which requires skipping initial xfb blast-off and instead propagating the values
using tmp variables at a later point
for the latter:
* the optimal way to do this is to unwrap the struct first to figure out what's being
emitted, at which point the value can be extracted and exported

This commit fixes the following flaws in the implementation:
* when a resource was re-allocated, the guest side storage
was also allocated
* when a source needs a readback before being written to, then
the call would go through vws->transfer_get, thereby bypassing the
staging resource, and this would fail on the host, because no
the allocated IOV was too small (just one byte)
* if the texture write would need neither flush nor readback, the
old code path would be used expecting that guest side backing stogage
for the texture.
v2: - actually do a readback to the stageing resource when it is required
- fix typo (Lepton)
v3: Don't use stageing transfers if the host can't read back the data
by rendering to an FBO or calling getTexImage, because in this case
we rely on the IOV to hold the date.
v4: Also don't use staging transfers if the format is no readback
format. Otherwise we have to deal with the resolve blit, and
this is currently not working correctly.
v5: add a new flag that indicates whether non-renderable textures can
be read back (either via glGetTexImage or GBM)
v6: Restrict the use of staging texture transfers to textures that can
be read back, and on GLES also if the they are bound to scanout and
the host uses minigbm to allocate such textures.
For that replace the flag indicating the capability to read back
non-renderable textures with a cap that indicates whether scanout
textures can be read back.
v7: update virglrenderer version in the CI
v8: update use of stageing (Chia-I)
v9: remove superflous check and assignment (Chia-I)
v10: disable stageing textures for arrays with stencil format. This is a
workaround for failures of the CI.
