Parallel: forbid beforeEach/afterEach at the top level of spec files

Each spec file is only loaded in a single worker, so top level
before/afterEach can't behave consistently.

beforeEach/afterEach are still supported in:
* Helper files
* describe() blocks
* At the top level of spec files in non-parallel mode
