160706aa387245ed96b1f13e5362fe1837e8fc4b logging, refactor: make category special cases explicit (Ryan Ofsky)
Pull request description:
* Move special cases from `LOG_CATEGORIES_BY_STR` to `GetLogCategory()` (suggested [here](https://github.com/bitcoin/bitcoin/pull/29419#discussion_r1547990373)).
* Remove `"none"` and `"0"` from RPC `logging` help because that help text was wrong. `"none"` resulted in an error and `"0"` was ignored itself (contrary to what the help text suggested).
* Remove unused `LOG_CATEGORIES_BY_STR[""]` (suggested [here](https://github.com/bitcoin/bitcoin/pull/29419#discussion_r1548018694)).
This is a followup to https://github.com/bitcoin/bitcoin/pull/29419, addressing leftover suggestions + more.

Code review ACK a7432dd6ed3e13a272d62ecde535e6d562cc932c. Only changes since last review are removing dead if statement and adding AJ's suggested -debug and -debugexclude help improvements, which look accurate and much more clear.
