ANDROID: KVM: arm64: Add PC_UPDATE_REQ flags covering all PC updates

Browse Source 
In order to deal with PC updates (such as INCREMENT_PC and the
collection of flags that come with PENDING_EXCEPTION), add a single
mask that covers them all.

This will be used to manipulate these flags as a single entity.
