Spec requires GPU release fences and CPU acquire fences at queue destroy.
Also update the recognized status codes.

Remove unused function (FenceRelease), add comments to barrier packet settings,
correct profiling controls to work with queue wrappers.

Move opening of DRM render nodes from topology to FMM aperture
initialization. Keep the same FDs open for the life time of the
process to match how KFD uses the VMs in the FDs. Call acquire_vm
ioctl during aperture initialization to let KFD use the VMs from
the render nodes.

Query GPUVM aperture limits of all dGPUs to determine SVM aperture
base and limit. This depends on a recent KFD change that reports
the GPUVM apurture limits for dGPUs in the
AMDKFD_IOC_GET_PROCESS_APERTURES_NEW ioctl (drm/amdkfd: Simplify
dGPU SVM aperture handling).
Only initialize SVM aperture once, instead of once per GPU.
Don't call AMDKFD_IOC_SET_PROCESS_DGPU_APERTURE. It's not needed any
more and will not be upstreamed.

Define dgpu_mem_init before it's used and keep the code close to the
rest of the aperture initialization code.

kfdtest hsaKmtOpenKFD failed after 1019 loop if using --gtest_loop=-1,
because default max open file handle limit is 1024. Found shmem file handle
is not closed from lsof output.

On discrete GPUs place the EOP queue in VRAM. The reader/writer of this
queue is the CP and the size is small. Dispatch latency improves
through lower read latency in AQL completion phase.

Invisible device memory is mmapped as PROT_NONE.
Normal CPU access to the memory is still not allowed but
struct vm_area_struct will be created for the memory address
so ptrace can access the memory via the vma.

UCX test cases are reporting uninitialized values when CMA fails. The
application should ideally ignore SizeCopied when the function fails but
it doesn't. This is leading to wrong diagnosis.
v2: Fill in partial SizeCopied in case of failure

New CMakeLists.txt sets a default module search so -DCMAKE_MODULE_PATH is
no longer required in the command.
