feat: add board M5Stack Tab5(ST7123).

[TinyuZhao]

Description

This PR adds board support for M5Stack Tab5(ST7123) under application/edge_agent/boards/m5stack/m5stack_tab5.

Summary of changes:

• Extend Tab5 board support to detect the panel type at runtime instead of assuming a single display stack.
• Add runtime selection between:
  • ILI9881C + GT911
  • ST7123 + ST7123 touch
• Add ST7123-specific display initialization commands.
• Update Tab5 display/touch factory logic to:
  • probe panel ID
  • apply variant-specific panel timing
  • instantiate the matching LCD driver
  • instantiate the matching touch driver

This board support also handles two known Tab5 display variants at runtime:

• ILI9881C + GT911
• ST7123 + ST7123 touch

Testing

Attempted local validation with the following commands:

idf.py -C application/edge_agent gen-bmgr-config -c ./boards -b m5stack_tab5
idf.py -C application/edge_agent flash monitor

Current status:

• Board manager generation for m5stack_tab5 succeeds.
• Firmware boots on Tab5 hardware.
• Runtime panel detection succeeds.
• ST7123 variant was detected and initialized successfully during local bring-up.
• LCD display and touch were both initialized successfully on tested hardware.
• Board manager completed initialization and provisioning AP started successfully.

Notes:

• Validation was performed on available Tab5 hardware during bring-up.
• This PR includes runtime handling for both known Tab5 display/touch variants, but local confirmation depends on hardware availability.
