test: clean up duplicated tests

[huozhi]

Clean up integration tests

• app-document: Merge multi fetch reuqests into 1, add checking for __NEXT_DATA__
• rsc/streaming: Merge duplicated tests, move the head tests to client-navigation since they're running under react 18 now
• remove runtime subtest suite under rsc tests since it's covered in switchable runtime test suite
