status_led: Kconfig migration

Move all of the status LED feature to drivers/led/Kconfig.
The LED status definitions were moved from the board configuration
files to the defconfig files.

TBD: Move all of the definitions in the include/status_led.h to the
relevant board's defconfig files.

Tested boards: CL-SOM-AM57x, CM-T335
