In most situations, JSONWriter users already know string lengths (either directly, or through `nsCString` and friends), so we should keep this information through JSONWriter and not recompute it again. This also allows using JSONWriter with sub-strings (e.g., from a bigger buffer), without having to create null-terminated strings. Public JSONWriter functions have overloads that accept literal strings. Differential Revision: https://phabricator.services.mozilla.com/D86192
