Add hsa_amd_vmem_address_reserve_align API

Browse Source 
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.
