MdeModulePkg ConSplitterDxe: Support toggle state sync

Browse Source 
Register key notify for toggle state (CapsLock, NumLock and ScrollLock)
sync between multiple keyboards.
The implementation for this feature requires keyboard driver supports
EFI_KEY_STATE_EXPOSED, and turns on physical TextInEx partial key
report for toggle state sync.
The virtual TextInEx will report the partial key after it is required
by calling SetState(X | KEY_STATE_VALID_EXPOSED) explicitly.
