  1. fabric: Add fi_hmem_attr to fi_info 

    FI_HMEM is only an on/off capability bit but there are more
specific capabilities. Add fi_hmem_attr to fi_info to provide
better control over:
- whether device API calls are permitted in libfabric, except for
FI_HMEM initialization.
- whether peer to peer transfers should be used.
- whether optimized memcpy for device memory should be used.
