Add hsa_amd_vmem_address_reserve_align API

New API to support alignment parameter when reserving virtual addresses.
If the alignment is 0, then the default size is used. Otherwise the
alignment needs to be a power of 2 and greater than or equal to page
size.

Existing hsa_amd_vmem_address_reserve marked for future deprecation.
