Adds non reader/writer based HAL 2.4 tests for AIDL composer3

If service exists then we can proceed with test otherwise tests will be skipped.

Test: atest VtsHalGraphicsComposer3_TargetTest but tests don't just work yet. as we don't have service implementation.
BUG: 202053621

NOTE: Efforts to migrate reader/writer based tests will be done under b/202446967
