nr pdcp: improve readability of integrity checking

Browse Source 
Introduce the structure nr_pdcp_integrity_data_t and adapt code to use it.

Note: in nr_pdcp_sdu_t we keep the 'count' variable (which is also present
in nr_pdcp_integrity_data_t). They represent the same value, but 'count'
in nr_pdcp_integrity_data_t is to be specifically used for integrity while
the other one has other uses, so it's better to keep it.
