Alex Sierra 96c0657383 tools: add selftests to hmm for COW in device memory 
The objective is to test device migration mechanism in pages marked as
COW, for private and coherent device type.  In case of writing to COW
private page(s), a page fault will migrate pages back to system memory
first.  Then, these pages will be duplicated.  In case of COW device
coherent type, pages are duplicated directly from device memory.
