Kernel: Remove is_sharing_with_others API from GenericInterruptHandler

is_sharing_with_others API was never really put to use properly since
it was introduced. The only place where it is used in Interrupts.cpp is
in conjuction with is_shared_handler() which is only true for
SharedIRQHandler and is_sharing_with_others will always return false.

Remove that API.
