ice: switch: convert packet template match code to rodata

Trade text size for rodata size and replace tons of nested if-elses
to the const mask match based structs. The almost entire
ice_find_dummy_packet() now becomes just one plain while-increment
loop. The order in ice_dummy_pkt_profiles[] should be same with the
if-elses order previously, as masks become less and less strict
through the array to follow the original code flow.
Apart from removing 80 locs of 4-level if-elses, it brings a solid
text size optimization:

add/remove: 0/1 grow/shrink: 1/1 up/down: 2/-1058 (-1056)
