move core tests to core (#3355)

* move core tests to core

* remove window

* fix up flaky tests

* test_entryfication needs a singly-threaded banking_stage

* move core benches to core

* remove unnecessary dependencies

* remove core as a member for now, test it like runtime

* stop running tests twice

* remove duplicate runs of tests in perf
