Add incompatible flag to guard top-level aspects dependencies This CL introduces `incompatible_top_level_aspects_dependency` flag to enable aspect-on-aspect and requiring aspects for command line aspects. This can be needed because the new behavior can break builds where a relation between top-level aspects existed (based on required_aspect_providers and provides) but it was never actually applied as it was not supported. One example of these cases: blaze build //:main --aspects=/tools:my_def.bzl%a1,/tools:my_def.bzl%a2 If aspect a1 provides a1p provider, aspect a2 requires a1p provider and the rule of target `main` also provides a1p. Once top-level aspect-on-aspect is enabled this build will fail because a1p will be provided twice to a2 (from a1 applied on `main` and from `main` target rule). Previously the relation between a1 and a2 was not detected and a2 used to get only the value of a1p from `main`'s rule. PiperOrigin-RevId: 390587290
