In scylladb/scylladb#19745, view_builder was migrated to group0 and since then it is dependant on group0_service.
Because of this, group0_service should be initialized/destroyed before/after view_builder.
This patch also adds error injection to `raft_server_with_timeouts::read_barrier`, which does 1s sleep before doing the read barrier. There is a new test which reproduces the use after free bug using the error injection.
Fixesscylladb/scylladb#20772scylladb/scylladb#19745 is present in 6.2, so this fix should be backported to it.
