Do this by refactoring out and reusing the logic that sets the "struct key_value_info" members when caching CLI config in a configset. This lets us get rid of the fake "struct config_source" in "git_config_from_parameters()", so we now only have to maintain one implementation. Additionally, this plumbing also reveals that "git_config_parse_parameter()" hasn't been setting either "the_reader.source" or "the_reader.config_kvi", so any calls to "current_*" would either BUG() or return *_UNKNOWN values. Also, get rid of the BUG() checks that forbid setting ".config_kvi" and ".source" at the same time, since we will run afoul of that check. They will soon be unnecessary when we remove ".source".
