OvmfPkg/XenBusDxe: Add InterlockedCompareExchange16.
This patch is inspired by InterlockedCompareExchange32 from the
BaseSynchronizationLib.
The function will be used in the "OvmfPkg/XenBusDxe: Add Grant Table
functions" patch.
Change in V3:
- Implement both .S and .asm, to get rid of GCC specific asm.
- Implement 32bit part of the assembly
Change in V2:
- Add intel compilation code
MSFT code is not compied over because I don't know how it works.
