StandaloneTestStrategy sets the full list of outputs on the test spawn All spawn strategies already treat all normal outputs as optional. Bazel checks at the action level whether all action outputs are created, but does not check at the spawn level. Spawn.getOptionalOutputs is therefore unnecessary, and removed in this change. The only place where this was set was in StandaloneTestStrategy, which now specifies the full set of outputs, which is now computed by TestRunnerAction. The internal test strategy implementations are also updated in this change. While I'm at it, also remove the use of BaseSpawn and use SimpleSpawn instead. This may go some way towards fixing #1413 and #942. -- PiperOrigin-RevId: 149397100 MOS_MIGRATED_REVID=149397100
