Metal provides straightforward ways to copy an image to/from memory,
and image-to-image copies can be implemented by chaining them.
Note that host copy of combined depth-stencil is not supported, as
Metal does not allow CPU copy for these formats. Additionally, GPU
optimized contents are not allowed with host image copy usage; CTS
directly initializes the raw memory of optimized images to random
invalid data, which appears to decompress differently on GPU vs CPU
and fail.

As most work for maintenance5 is already done in the common Vulkan
runtime, functions required by it are implemented in pvr driver and
blitting functions are changed to use common functions for acquiring
subresource layer count, advertise VK_KHR_maintenance5 now.

This extension is part of Vulkan 1.2 core and the feature is already
exposed; we just weren't advertising the extension separately.

f4812dc1 introduces optimizations that turn ior into bcsel. The MSL
compiler will incorrectly compile the shader internally when bcsel is used
leading to incorrect outputs. This commit adds a workaround that tricks
the MSL compiler into correctly compiling the shader internally.

Metal provides device properties for the recommended maximum memory usage and
the current amount of memory used. These can be used to provide an estimate
of heap usage and calculate a budget of memory usage by the application before
performance may degrade.

We've been reporting in features.txt that we support this extension
unconditionally, but we didn't. Now that we have the bits wired up due
to Vulkan, we can actually enable it on Bifrost and later.

GPU capture bugs if heap sizes are not aligned to at least 16K. Ensuring that
they are is not expected to impact memory usage since it seems the actual
internal memory allocation is already aligned to 16K, the issue is only with
how the heap reports its size versus the allocation size that capture uses.
