Clean up dumpstate HAL 1.1 VTS test.

We separate out per-mode tests into a separate test suite for better
extensibility. If a new DumpstateMode value is added to 1.1, it will no
longer require updating a macro in the test.

All tests still run the same and if they're per-mode, still include the
actual mode string in their final name. No material behavior changes.

Test: atest VtsHalDumpstateV1_1TargetTest on cuttlefish
