SF: Return EX_CONFIG_FAILED from setActiveConfigWithConstraints()

setActiveConfigWithConstraints() currently returns V2_4 Hal::Error
But with the new Composer3 IcomposerClient AIDL changes, it should
return int32_t corresponding the new EX_CONFIG_FAILED
exception. So define a new enum class Error to handle all V2_1  and 2_4
errors and the new IcomposerClient exception.

Also define a new class to return the result of initiateModeChange
as: Changed, Rejected, Aborted.

So change this plumbing through SF. Catch this error and propagate
up from DisplayModeController to SF using Scheduler
