* libhsakmt: Update hsakmt_fmm_get_handle to support address range
Currently, hsakmt_fmm_get_handle works only if the address is allocated
(staring) value. Update it so it can find the handle if address falls in
the valid allocated range. This is useful for AMD infinity storage
feature where data needs to be transferred to any memory within in the
allocated range

* libhsakmt: Introduce AMD Infinity Storage (AIS) API
Add hsaKmtAisReadWriteFile() API to support AMD Infinity Storage. The
API moves data directly from GPU VRAM to a file.
v2: Add in/out ioctl arguments to provide more status information to
user space. Modify hsaKmt API also accordingly.
