vppinfra: bihash improvements
Template instances can allocate BIHASH_KVP_PER_PAGE data records
tangent to the bucket, to remove a dependent read / prefetch.
Template instances can ask for immediate memory allocation, to avoid
several branches in the lookup path.
Clean up l2 fib, gpb plugin codes: use clib_bihash_get_bucket(...)
Use hugepages for bihash allocation arenas
Type: improvement
