71cdcb7756 sys: util: Update implementation of loop macros
Recursive macros are more generic but they are very depending for
preprocessor. When they are used extensively they can prolong
compilation even ten times. Replaced them with brute force
implementation for:
- FOR_EACH macros
- GET_N_ARG
- GET_ARGS_LESS_N
- UTIL_LISTIFY
- UTIL_REPEAT

New implementation provides same functionality but it is limited to 64
input arguments. This is not a hard limitation and can be increased
in the future.
