Adds the thunk include and lib paths to the cache, removes paths
to indicator files from the cache, uses the cached path directory
(if any) as a search hint for indicator files.

Because of HW design change, GPUVM aperture is no longer needed on GFX9
APUs. However, on APUs some functionalities still depend on GPUVM
aperture, so we choose to use SVM aperture instead to assume
the functionality of previous GPUVM aperture.

[ROCm/ROCR-Runtime commit: cb4814eadc]
Marking heap memory as executable using mprotect() is not allowed
by SELinux. mprotect() calls that try to do this will fail on systems
with SELinux enabled. This is also a security risk, so it should be
fixed even on systems that allow this.
Any memory we want to mark as executable must be allocated using mmap().
See https://www.akkadia.org/drepper/selinux-mem.html
The two places where we try to mark heap memory as executable both use
posix_memalign() to allocate the heap memory. In both cases, the
alignment value passed into this function is always equal to PAGE_SIZE,
which means that they are safe to replace with mmap(), which guarantees
alignment to PAGE_SIZE. In this case PAGE_SIZE has been set to
sysconf(_SC_PAGESIZE);
v2:
- Use MAP_PRIVATE instead of MAP_SHARED. This matches the behavior
of memory allocated by posix_memalign()
- Ignore alignment hints instead of returning error when we can't
accommodate them.
- Drop alignment parameter of allocate_exec_aligned_memory() since
the only alignment supported is sysconf(_SC_PAGESIZE).
- Remove extra parameter from fmm_release().
- Add error path to fmm_allocate_host_cpu() for when mmap fails.
v3:
- Avoid use after free.

TensorFlow was running out of VRAM due to padding up allocations
from legacy memory APIs. These allocations have been added to
the fragment allocator to improve VRAM utilization.

Since access may only be manipulated on whole pages, suballocator fragments must cooperate to set the page's access.
Since the KFD does not migrate memory on access changes this implementation makes agent access sticky across the requests in a fragmented page.

Blocks inside of HsaCounterProperties structure is not a fixed size. It
varies with number of counters in the block -- size of Counters in
HsaCounterBlockProperties is different in every block. Current
implementation assumes fixed size and the next block will overwrite the
previous block's Counters. This patch change the array implementation to
using a pointer so it'll move the next block to the correction position.

Applications may try to allocate lots host memory and reaches the mmap
limit (/proc/sys/vm/max_map_count). When Applications fails to allocate
memory and calls hsaKmtFreeMemory to release the memory, Thunk fails to
reduce the maps count so the following hsaKmtAllocMemory calls continue
to fail, which doesn't make sense to the application. This patch checks
the mmap to NORESERVE return value. If it fails and the error number is
ENOMEM, reduce the map count by munmap and map it again immediately.
