This is needed because after changing default language version to 2.0, we still need to test many scenarios from this test in K1. Move K1-specific tests to OldCompileKotlinAgainstCustomBinariesTest, and K2-specific tests to FirCompileKotlinAgainstCustomBinariesTest. Mute failing K2 tests via `muteForK2`. It will throw exception if the muted test will suddenly start passing.
