Introduce FDB Source User Meta for ACL Table

Assign values to sai_fdb_entry_attr_t enum fields

This patch:

opencomputeproject#1259 introduced
explicit numbering to enum fields to avoid breaking warmboot across SAI
spec enhancements while maintaining readability. It fixed saiacl.h and
saihash.h.

Introduce similar explicit numbering for enum sai_fdb_entry_attr_t.
Subsequent stacked commit needs to insert a new enum field in the
middle.
