tool_getparam: refactored, simplified

- add dedicated option functions for bools/none/strings
- simplify clearing (some) arguments, use '*' instead of ' '
- scripts/top-complexity: remove getparameter from whitelist
- handle --help separately
- getstr and getstrn do not allow a NULL input
- improve the ;auto check, it needs to be trailing
- add toggle bit helper function
- unify an error message for bad --no- use
- introduce generic handling of deprecated options: ARG_DEPR
- handle --no- prefix on more booleans:

    --cert-status
    --doh-cert-status
    --false-start
    --mptcp
    --ssl-no-revoke
    --ssl-revoke-best-effort
    --tcp-fastopen
