freertos: Refactor component structure

This commit refactors the "freertos" component's structure as follows:

- "FreeRTOSConfig.h" related files moved to "./config" directory
- Refactored CMakeLists.txt file in preparation for v10.5.1 upgrade
    - Grouped list appends based on component organization
    - Removed some unecessarily public "include_dirs"
- Removed FreeRTOS-openocd.c
    - uxTopUsedPriority has been added back to tasks.c since v10.4.2
    - Thus the workaround in FreeRTOS-openocd.c is no longer needed and can
      be removed.
