Support Hardware V2

[gabryelreyes]

USB Host driver is not implemented yet. Will be done in a separate PR. See #217

[Copilot]

Pull request overview

This PR adds support for Hardware V2 by introducing the HALTargetV2 library, which provides hardware abstraction for an ESP32-S3 based platform. The implementation is largely a copy of the existing HALTarget with adaptations for new GPIO pin assignments and button handling.

Key Changes:

• New HALTargetV2 library implementing hardware abstraction for ESP32-S3 platform
• New PlatformIO build environments for ESP32-S3 target (RemoteControlTargetV2)
• Hardware drivers for network, MQTT, USB host, robot communication, LEDs, buttons, battery monitoring, and file system

There is much more code that could be in a common HAL to keep the specific HAL as small as possible.
