This hoists all the annoyance of figuring out the current pixel's input
attachment coordinates to the driver. The pass still deals with all the
annoyance of turning an image instruciton into a texture instruction but
it gives the driver more control over the position. For most drivers,
this will be something like ivec3(int(gl_FragCoord.xy), gl_Layer) or
similar, some drivers need something more nuanced. Turnip, for
instance, needs unscaled coordinates for some attachments and NVK
doesn't really want gl_Layer or gl_ViewIndex for the layer. It's better
to just have a new system value that drivers can make what they want.

The SPIR-V spec is pretty clear that coordinates on subpass attachments
are relative to the current pixel. They're required to be zero but we
should stay consistent with ourselves (we already do this for image
intrinsics) and with the spec.

This moves some conversions to NIR that may get eliminated, and also
distinguishes gl_FragCoord.z/w loads at the shader info level so we don't
need to flag uses_src_depth/uses_src_w when only gl_FragCoord.xy get used
(as is typical). This reduces thread payload setup on many shaders.
Also, interestingly, blorp shaders stop reserving space for z/w despite
not putting them in the payload (since PS_EXTRA isn't filled out for z/w).

This generates one extra instruction to set the rounding mode to RTE due
to f2f16_rtne in the lowering. This changes the result for
fquantize2f16(65505.0) from 65536 to 65504, which fixes SPIR-V
conformance for this value:
If Value is positive with a magnitude too large to represent as a
16-bit floating-point value, the result is positive infinity. If Value
is negative with a magnitude too large to represent as a 16-bit
floating-point value, the result is negative infinity.
SPIR-V doesn't specify whether this overflow check is before or after
rounding, but IEEE specifies rounding first, which is what produces our
65504.

There's no need for a per driver HMI implementation since the
vk_icdGetInstanceProcAddr implementation can well populate the required
entrypoints for Android icd.
Changes have to be done in this single commit for simplicity. Otherwise,
I would have to create a separate android shared library in the runtime
like how vk_instance is handled today, so that the target is able to
check per driver enablement def. However, after all drivers have
migrated over within this MR, we still have to clean those up. So I
decided to just do those in a single commit instead.
