MdeModulePkg/Capsule: Remove RT restriction in UpdateCapsule service.
Current UpdateCapsule service will reject all non-reset capsule images and
return EFI_OUT_OF_RESOURCE if the system is at runtime. This will block a
platform CapsuleLib from implementing ProcessCapsuleImage() with runtime
capsule processing capability.
This patch removes this restriction. The change is controled by a feature
PCD PcdSupportProcessCapsuleAtRuntime, and the default value is FALSE
which means not enable this feature.
