Mark some subgop unit tests as 'Large'.

These tests are very slow, so we mark them as Large. That way, they are
only run nightly, and NOT per-commit.
- SubGopSwitchingTest and
- SubGopPSNRCheckTest

e.g. AV1/SubGopSwitchingTest.SubGopSwitching/0 takes 3350331 ms = 56 min
and  AV1/SubGopPSNRCheckTest.SubGopPSNRCheck/6 takes 1358767 ms = 23 min

Related: reduce number of frames encoded in SubGopSwitchingTest to
roughly halve the time for that (for nightly tests).
