People who use RADV on eGPU have reported poor performance by default.
They also noted that the "nosam" option helps.
This commit disables placing CS objects in VRAM when the bandwidth is
below that of PCIe 3.0 x8. Note that eGPUs are typically PCIe 3.0 x4.

To fix a hypothetical issue:
v0 = start_linear_vgpr
if (...) {
} else {
use_linear_vgpr(v0)
}
v0 = phi
We need a p_end_linear_vgpr to ensure that the phi does not use the same
VGPR as the linear VGPR.
This is also much simpler.

Shader binaries that are imported during linking should already be in

Zink creates all libaries with CREATE_RETAIN_LINK_TIME_OPTIMIZATION,
then it first creates unoptimized pipelines and it enqueues optimized
pipelines in the background with CREATE_LINK_TIME_OPTIMIZATION.
If a pipeline is linked without CREATE_LINK_TIME_OPTIMIZATION, the
driver should import binaries instead of retained NIR shaders. This
was broken because RADV wasn't compiling binaries at all in presence
of CREATE_RETAIN_LINK_TIME_OPTIMIZATIONS. Now, it always compiles
binaries in libraries but can also retain NIR if requested.

ac/surface puts the raw pip_bank_xor there, which needs the extra
shift for the actual tile_swizzle.
(I think long term we should refactor this in ac/surface but for
now lets fix like radeonsi to avoid race conditions.)

This introduces radv_compute_pipeline_compile() which is used for
compute and ray tracing pipelines. I think it's better than having a
single function for compiling everything, and that will allow us to do
more cleanups.

The Vulkan spec says:
"VK_PIPELINE_CREATE_FAIL_ON_PIPELINE_COMPILE_REQUIRED_BIT specifies
that pipeline creation will fail if a compile is required for
creation of a valid VkPipeline object; VK_PIPELINE_COMPILE_REQUIRED
will be returned by pipeline creation, and the VkPipeline will be
set to VK_NULL_HANDLE."
Given the implementation is expected to set the pipeline to
VK_NULL_HANDLE, it's unecessary to handle pipeline feedback.

to full dynamic rendering, the framebuffer dimensions is no longer used.
Forcing the render area to be the framebuffer dimensions restore the
previous logic and it fixes rendering issues.

The meson.build_root() method has been deprecated, so let's switch to
meson.project_build_root(), which usually means the same thing. The case
where it doesn't do the same thing is if Mesa is a subproject to some
other project, but in that case I believe we want the build root of Mesa,
not of the parent project anyway.
