New kernel drivers, filesystem API, and more (#513)

* **New Features**
  * BMI270 6-axis IMU driver added; new unified filesystem abstraction for mounted filesystems.
  * Public Wi‑Fi API surface (no implementation yet)
  * SDMMC driver added (kernel drive$)
  * expanded GPIO interrupt/callback support
* **Improvements**
  * M5Stack Tab5: revamped GPIO/power initialization and IMU integration.
  * LVGL updates including device fontSize configuration.
  * Updated all code related to SD card device/fs handling
  * Rename LilyGO T-HMI S3 to LilyGO T-HMI
* **Bug Fixes**
  * Simplified and consolidated SD card handling and mount discovery.
