Adam Benhassen 01af8484b1 feat: add M5Stack Cardputer ADV board support ...

Add support for the M5Stack Cardputer ADV hardware variant, which
replaces the original GPIO matrix keyboard with a TCA8418 I2C keypad
controller.

Changes:
- Vendor Adafruit_TCA8418 library for I2C keyboard communication
- Add MARAUDER_CARDPUTER_ADV board target with feature flags in configs.h
- Implement TCA8418 keyboard driver with interrupt-driven FIFO scanning,
  coordinate remapping (verified against M5Cardputer-UserDemo-ADV), and
  persistent key state tracking for compatibility with menu polling
- Extend all MARAUDER_CARDPUTER preprocessor guards to include ADV variant
- Add TFT_eSPI display configuration (same display as original Cardputer)
- Add CI build matrix entries for both parallel and nightly workflows
