ARM: Introduce ARM_DEFAULT_SHORT_ENUMS

Allow targets to define the default for the short enums option.

gcc/

	* config/arm/arm.h (ARM_DEFAULT_SHORT_ENUMS): Provide default
	definition.
	* config/arm/arm.c (arm_default_short_enums): Use
	ARM_DEFAULT_SHORT_ENUMS.
	* config/arm/rtems.h (ARM_DEFAULT_SHORT_ENUMS): Define.
