ROCr internally uses the same allocation_map_ list to track memory
allocations that are both for internal allocations and allocations by
users of ROCr library. In some edge cases, the library user would call
hsa_amd_pointer_info on an invalid pointer, but ROCR would return the
pointer as valid because this pointer belongs to a memory range that
was allocated internally within ROCr. Adding a flag to differentiate
between internal and external allocations.

Fixes hang due to change in order of initialization of libraries
that have cyclical dependencies and they call hsa_init() during their
initialization phase.
This implementation looks for a symbol called "HSA_AMD_TOOL_PRIORITY"
across all loaded shared libraries using dynamic section entries of the
loaded lib instead of using dlopen and dlsym for the same purpose.

Currently, Wavefront::GetInfo(HSA_WAVEFRONT_INFO_SIZE.. always returns
64. Instead, return the proper wavefront size based on the ISA.
Temporarily, we only return 1 wavefront size for each ISA. As we do not
have mechanism from upper layers to determine correct wavefront when
there are multiple wavefronts supported. We are temporarily
returning 32 for all gfx1xxx cards even though they support 64 as the
kernels for gfx1xxx are compiled for wavefront-32 by default.

Thunk keeps an internal cache of system topology that can be used to
speed up subsequent calls to hsaKmtAcquireSystemProperties(). This cache
is cleared by calling hsaKmtReleaseSystemProperties() at the beginning
of BuildTopology().
hsaKmtRuntimeEnable() also calls hsaKmtAcquireSystemProperties() inside
Thunk. Move call to hsaKmtRuntimeEnable() after BuildTopology() so that
we can re-use Thunks internal cache.
Parsing of of topology can take ~150 ms on systems for large number of
nodes.

MES devices need GART mappings and therefore need non-paged memory. But
using non-paged memory introduces performance regression where it can
take over 80 ms to see the signal changes if the memory is in the wrong
NUMA node. Currently, we cannot control NUMA affinity when allocating
non-paged memory. Using non-paged memory allocation only on devices that
have MES scheduler

If a user queries the pointer info on an invalid pointer,
hsaKmtQueryPointerInfo will return error or unknown pointer. The other
fields in HsaPointerInfo are invalid, so we do not return them to the
user.
Also removing the assert and returning unknown pointer instead. As the
assert will not trigger in release builds.
hsaKmtQueryPointerInfo may also return unknown pointer for userptrs as
they are not always tracked by thunk. Adjusting code to still treat
these pointers as valid in this case.

The allocation logic of the SPI does not take into account compute
user thread management settings for masking CUs with the exception of
skipping fully disabled SEs. This means that occupancy limited
dispatches such as cooperative launch may over allocate onto hardware
resources that are not immediately available, resulting in a potential
barrier logic hang as occupying work groups are waiting on enqueued
work groups to reach the barrier.
Further work will have to be done to get the per-SA CU enablement count
from the KFD in order to correctly clip the cooperative CU limit based
on the CU mask, which will require breaking the current ABI.
For now, report that cooperative launch is not supported while a CU
mask has been applied to prevent potential shader hangs.
