Implement resource_get_param for PIPE_RESOURCE_PARAM_NPLANES and fix
resource_get_handle to walk to the correct linked resource for
multiplanar images, allowing gbm_bo_get_handle_for_plane to be called
with plane > 0.
This fixes an assert that is triggered when a wayland client tries
to send weston an NV12 dmabuf, for example:
weston: .../mesa/src/gbm/backends/dri/gbm_dri.c:752: gbm_dri_bo_get_handle_for_plane: Assertion `plane == 0' failed.

When we bring up the Valhall compiler in Mesa, we will like to have a
disassembler in native code, so we shouldn't write our disassembler in
Python. Instead, we write a disassembler generator in Python with mako
templates, which will produce a va_disasm_instr entrypoint from the
architecture defined in ISA.xml and valhall.py.

This Python script acts as a standalone assembler. It takes Valhall
instructions with Mesa-flavour syntax, parses them, errors out if there
are syntax errors, and writes out an assembled binary if there are not.
It also is available as a programmatic interface for automated testing.
While this attempts to handle syntax errors, it does not check
semantics. It will happily compile programs that fault, provided each
instruction locally 'looks' plausible.
The code itself is quite small, despite supporting most of the known
ISA, because the syntax is regular and the heavylifting is done by
ISA.xml and valhall.py.

The code in dri_make_current just checks the value of the pointers
to decide to update texture_stamp or not. This is buggy since a new
allocated drawable could share the same address with the previous
released drawable. Fix the stale pointer issue by always resetting
these pointers to NULL in dri_unbind_context.

The current code we have for this is a bit of a mess, likely due to
trying too hard to put it in anv_android.c. The external_format bit in
anv_image, for instance, really means "quit creation early" which is
something we want to do for AHardwareBuffer imports regardless of
whether or not they use a native format. It gets set both by declaring
an AHardwareBuffer external handle type and by VkExternalFormatANDROID.
However, VkExternalFormatANDROID is only allowed for AHardwareBuffer
imports. If we ever did get an external format outside the context of
an AHardwareBuffer import, we would end up with a useless partially
created image.
When we detect an AHardwareBuffer import, we punt off to a function in
anv_android.c that does nothing interesting but call anv_create_image
with AUX disabled and external_format = true. The aux disable here is
useless because the actual isl_surf layout is done by resolve_ahw_image
which also sets ISL_SURF_USAGE_DISABLE_AUX_BIT. As far as external
formats go, anv_image_from_external() sets it regardless of whether or
not there is actually an external format.
This commit replaces anv_image::external_format with anv_image::from_ahb
which is the thing we actually want to track for this. We delete
anv_image_from_external and a bunch of the external_format handling
because it's all useless. The end result is massively simpler and,
while it appears to blur the boundary between Android code and the rest
of the driver, it makes the whole flow more obvious.
