Starting with a750, the ALWAYS_ON counter is initialized from a loadable
counter in CX power domain, which is never turned off except during a
GPU reset. This means that timestamps should always be monotonic except
if the GPU resets, in which case subsequent submits should return
DEVICE_LOST anyway. Thus it should be good enough to satisfy the Vulkan
requirement that vkCmdWriteTimestamp is monotonic.
kgsl tries to synchronize the CX counter to the CPU counter, and
additionally adds a synchronization ioctl to improve the accuracy. I'm
not sure whether the former is really useful for us, but the latter
should eventually be implemented in drm/msm. However for now we can
expose the extension without any kernel support.

Zink currently requires VK_EXT_queue_family_foreign to set
PIPE_CAP_DMABUF, which is one of the requirements to create a
gbm context.
v3dv already conditionally supported this extension for Android.
As it is now required for Zink in Mesa, move it to the driver's
common set.
This allows v3dv to create gbm contexts with Zink again since
this was made a stricter requirement as a side effect of
ab08b79ef7 ("gbm: use driver check for dmabuf export").
Tested with Zink on a gbm EGL application as well as sway with
the wlroots Vulkan backend, which also requires this extension.

Previously we tried to map GPU resources directly wherever we could,
however this was always causing random issues and was overall not very
robust.
Now we just allocate a staging buffer on the host to copy into, with some
short-cut for host_ptr allocations.
Fixes the following tests across various drivers:
1Dbuffer tests (radeonsi, zink)
buffers map_read_* (zink)
multiple_device_context context_* (zink)
thread_dimensions quick_* (zink)
math_brute_force (zink)

Add basic KHR_8bit_storage support for Adreno 750 devices, for now enabling
the storageBuffer8BitAccess feature. A separate descriptor is provided for
8-bit storage access. The descriptor index is adjusted appropriately for
8-bit SSBO loads and stores.
The 8-bit SSBO loads cannot go through isam since that instruction isn't
able to handle those. The ldib and stib instruction encodings are a bit
peculiar but they match the blob's image buffer access through VK_FORMAT_R8
and the dedicated descriptor. These loads and stores do not work in
vectorized form, so they have to be scalarized. Additionally stores of
8-bit values have to clear up higher bits of those values.
8-bit truncation can leave higher bits as undefined. Zero-extension of
8-bit values has to use masking since the corresponding cov instruction
doesn't function as intended. 8-bit sign extension through cov from a
non-shared to a shared register also doesn't work, so an exception is
applied to avoid it.
Conversion of 8-bit values to and from floating-point values also doesn't
work with a straightforward cov instruction, instead the conversion has
to go through a 16-bit value.
