feat: Port GPIO visualization and ASP v2.0 telemetry to MegaMax and MiniMax

[riteshrajas]

Ported the new ASP v2.0 protocol features, GPIO visualization logic, and pin state reporting from MicroMax and Horizon to the MegaMax (L3) and MiniMax (L2) projects.

• Added an overloaded buildTelemetryPayload to MiniMaxRuntime.h to accept pin states and format them as an ASP v2.0 pins object.
• Mapped system pin states (kMotionPin, kAirQualityPin, kLightPin) in MiniMax/src/main.cpp for GPIO telemetry tracking.
• Added a pins object dictionary with default pins (MODEM_RX, MODEM_TX, BAT_ADC) in MegaMax/src/ApexProtocol.cpp to correctly output pin visualization to Horizon.
• General sweep to ensure correct JSON formatting in telemetry packets and valid logic in string parsing logic for both C++ bases.
• Committed the changes inside the respective git submodules and updated their references in the parent tree.
