v2.16.0 add support to RP2040 and RP2040W boards

### Release v2.16.0

1. Add support to **RP2040-based boards, such as Nano_RP2040_Connect, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040**, using WiFiNINA or Ethernet
2. Add `WS` and `BearSSL WSS` support to `RP2040W` using `CYW43439 WiFi` with `arduino-pico` core
3. Optional user-defined 
- `WEBSOCKETS_TCP_TIMEOUT`, default 5,000ms
- `EIO_HEARTBEAT_INTERVAL`, default 20,000ms
- `SIO_PING_INTERVAL`, default 60,000ms
- `SIO_PONG_TIMEOUT`, default 90,000ms
- `SIO_DISCONNECT_TIMEOUT_COUNT`, default 5
4. Update `Packages' Patches`
