This hunts down several places around packet templates/dummies for
switch rules which are either repetitive, fragile or just not
really readable code.
It's a common need to add new packet templates and to review such
changes as well, try to simplify both with the help of a pair
macros and aliases.
ice_find_dummy_packet() became very complex at this point with tons
of nested if-elses. It clearly showed this approach does not scale,
so convert its logics to the simple mask-match + static const array.

bloat-o-meter is happy about that (built w/ LLVM 13):

Diffstat also looks nice, and adding new packet templates now takes
less lines.

We'll probably come out with dynamic template crafting in a while,
but for now let's improve what we have currently.
