l2: performance enhancement in l2input

Short Load/Stores combined with prefetching in the beginning of the loop
place too much pressure on AGUs and memory accesses.
The patch interleaves load/store operations with computational operations
to alleviate the pain point.

vlib_get_buffers is also leveraged.

Redefine u8 dst_and_src[12] instead of dst[6] and src[6] in struct
l2input_trace_t in order to merge two copys into one.

Type: improvement
