Fix &ice_parser_rt::bst_key size. It was wrongly set to 10 instead of 20
in the initial impl commit (see Fixes tag). All usage code assumed it was
of size 20. That was also the initial size present up to v2 of the intro
series [2], but halved by v3 [3] refactor described as "Replace magic
hardcoded values with macros." The introducing series was so big that
some ugliness was unnoticed, same for bugs :/
ICE_BST_KEY_TCAM_SIZE and ICE_BST_TCAM_KEY_SIZE were differing by one.
There was tmp variable @j in the scope of edited function, but was not
used in all places. This ugliness is now gone.
I'm moving ice_parser_rt::pg_prio a few positions up, to fill up one of
the holes in order to compensate for the added 10 bytes to the ::bst_key,
resulting in the same size of the whole as prior to the fix, and minimal
changes in the offsets of the fields.
Extend also the debug dump print of the key to cover all bytes. To not
have string with 20 "%02x" and 20 params, switch to
ice_debug_array_w_prefix().
This fix obsoletes Ahmed's attempt at [1].

Add API ice_parser_profile_init() to init a parser profile based on
a parser result and a mask buffer. The ice_parser_profile struct is used
by the low level FXP engine to create HW profile/field vectors.

Add new parser module which can parse a packet in binary and generate
information like ptype, protocol/offset pairs and flags which can be later
used to feed the FXP profile creation directly.
Add skeleton of the create and destroy APIs:
ice_parser_create()
ice_parser_destroy()
