If the GPU-side storage has been written to without using cpu_storage,
then we have to initialize the CPU-side storage correctly.
This requires a sync + copy but it's a one time operation so it shouldn't
affect performance much.
I don't think it fixes any existing bug, but the next commit will need
this to behave correctly.

This should fix a performance regression with the internal kernel
branch which does not support the upstream I915_MMAP_OFFSET_FIXED.
With I915_MMAP_OFFSET_FIXED we defer the mapping flags to the kernel
since it knows better where buffers are going to end up (lmem or smem).
The internal kernel doesn´t have that and there we should use write
combined for anything that can be in lmem.

As monotonic_buffer_resource is not thread-safe,
we use a thread_local instance which gets allocated once.
This change reduces the compile time spent in ACO by
approximately 10%.

This basic allocator implements an arena allocation strategy
and cannot free individual allocations.
It is intended for very fast memory allocations in situations
where memory is used to build up a few objects and then is
released all at once.
This class mimics std::pmr::monotonic_buffer_resource.

Things are a bit confusing because we use the term "scratch" for 2
different things :
* the buffer for register allocation spilling
* the buffer for storing live values between splitted shaders around shader calls
Here we're fixing the missing register allocation spilling buffer.

GRL, or Graphics Library for Ray-tracing is a library we share with the
Windows drivers for doing BVH builds on the GPU. It consists of a few
headers shared between CL and C code, a bunch of CL kernels, and some
GRL meta-kernels in their own format.

Since divergence is a lot more likely in RT than compute, it makes
sense to limit ourselves to SIMD8.
The trampoline shader defaults to SIMD16 since this one is uniform.
