kernel: improve BlockChecked ownership semantics

Browse Source 
Subscribers to the BlockChecked validation interface event may need
access to the block outside of the callback scope. Currently, this
is only possible by copying the block, which makes exposing this
validation interface event publicly either cumbersome or with significant
copy overhead.

By using shared_ptr, we make the shared ownership explicit and allow
users to safely use the block outside of the callback scope.
