logging, refactor: make category special cases explicit

Make special cases explicit in GetLogCategory() and LogCategoryToStr()
functions. Simplify the LOG_CATEGORIES_BY_STR and LOG_CATEGORIES_BY_FLAG
mappings and LogCategoriesList() function.

This makes the maps `LOG_CATEGORIES_BY_STR` and `LOG_CATEGORIES_BY_FLAG`
consistent (one is exactly the opposite of the other).
