feat(radio): add more power LED color overrides

[qkdxorjs1002]

Summary of changes:

Support additional POWER_LED_* build options and validate that only one color override is enabled at a time. Extend the generic STM32 LED driver to handle RGB combinations for yellow, magenta, and cyan. (except red)

Summary by CodeRabbit

• New Features
  • Expanded power LED color configuration options (Green, Cyan, Yellow, Magenta, White) in addition to Blue.
  • Added support for new LED color controls across multiple hardware platforms.
  • Status LED behavior now maps the selected power LED color into the corresponding error/end indication.
• Bug Fixes
  • Build validation now ensures only one power LED color override is enabled at a time.
  • Added clearer build-time checks to prevent enabling power LED overrides without required status-LED support.

📝 Walkthrough

Walkthrough

The PR expands power LED selection from blue-only to six compile-time colors. It adds RGB driver functions, board-specific declarations and startup wiring, status LED capability validation, strip support, and corrected option preprocessor conditionals.

Changes

Power LED Color Selection Extension

Layer / File(s)	Summary
Build configuration for power LED colors radio/src/CMakeLists.txt	Adds five color options, rejects multiple selections, and emits compile definitions for enabled colors.
LED driver RGB implementation and color functions radio/src/boards/generic_stm32/led_driver.cpp, radio/src/boards/*/board.h, radio/src/targets/*/board.h, radio/src/targets/{pa01,pl18}/led_driver.cpp	Centralizes generic RGB GPIO control and adds yellow, magenta, cyan, and white functions for generic and strip-based drivers.
Board build and startup integration radio/src/targets/{pa01,pl18}/CMakeLists.txt, radio/src/targets/pa01/board.cpp, radio/src/boards/{jumper-h750,rm-h750}/board.cpp	Enables STATUS_LED_STRIP for PA01 and PL18 and updates PA01 startup LED selection; remaining board edits are formatting-only.
Status LED macros and option wiring radio/src/edgetx.h, radio/src/options.h	Maps configured colors to status LED behavior, validates color capabilities at compile time, and fixes POWER_LED conditional closures.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Inline comments:
In `@radio/src/edgetx.h`:
- Around line 618-620: In the LED macro fallback `#else` block, add a LED_BIND()
definition alongside LED_ERROR_END(). Assign it the appropriate fallback LED
color used by this branch so callers such as bind_button_driver.cpp compile
successfully when no green LED is available.
- Around line 594-596: Add a capability validation branch alongside the existing
POWER_LED_GREEN check in the preprocessor configuration, using POWER_LED_BLUE
and the board’s corresponding blue-LED capability macro. Emit a compile-time
error when POWER_LED_BLUE is explicitly enabled without supported blue LED
hardware, while preserving the existing green validation.

In `@radio/src/targets/pa01/board.cpp`:
- Around line 389-393: Replace the conditional power-LED selection in
radio/src/targets/pa01/board.cpp lines 389-393 and
radio/src/boards/rm-h750/board.cpp lines 171-175 with exhaustive preprocessor
mapping: each POWER_LED_BLUE, POWER_LED_GREEN, POWER_LED_YELLOW,
POWER_LED_MAGENTA, POWER_LED_CYAN, and POWER_LED_WHITE macro must invoke its
corresponding led*() function, preserving the correct selection for every
supported color.
