Enrich the Skyframe exception handling API with methods that promote code reuse and request batching. While refactoring `AspectFunction`, I've noticed that Skyframe requests may be suboptimally batched when different keys throw different exception types because the author probably felt that batching them introduced too much complexity. Another pattern I'm seeing is the use of helper functions which may expect only a certain exception type and/or arity of `ValueOrExceptionN`, leading to suboptimal batching to fit the method's requirements. An example is `ConfiguredTargetFunction#computeDependencies`, where aspects are not requested along with configured targets - requesting them together would make calling into the helper function `ConfiguredTargetFunction#resolveConfiguredTargetDependencies` difficult. The new methods in this change already have some use cases and will additionally allow me to batch configured target and aspect requests as mentioned above without introducing code duplication.
