feat(mobile): native clients (#21459)

* platform clients * uppercase http method * fix hot reload * custom user agent * init before app launch * set defaults * move to bootstrap * unrelated change * disable disk cache by default * optimized decoding * remove incremental * android impl * memory optimization * lock approach is slower on ios * conditional cronet * clarify parameter * enable disk cache * set user agent * flutter-side decode * optimized http * fixed locking * refactor * potential race conditions * embedded cronet * refactor, fix capacity handling * fast path for known content length * ios optimizations * re-enable cache * formatting * bump concurrency * clear cache button * fix eviction race condition * add extra cancellation check * tighten dispose * better error handling * fix disposal --------- Co-authored-by: Alex <alex.tran1502@gmail.com>
