Automated rollback of commit a2cbc1f4b4303e4e7df927650b46225fdedc7ff2. *** Reason for rollback *** Make some internal metrics worse: the new code creates new NestedSet instances for each CppCompileAction and if the set of includes of a CppCompileAction are unique, this results in a lot of new nested sets with potentially a lot of new direct members and thus Skyframe edges. *** Original change description *** Share discovered input dependencies (#31767) ActionExecutionFunction records shared discovered inputs as ArtifactNestedSetKey dependencies instead of retaining a separate Skyframe edge for every discovered artifact. ActionRewindStrategy receives the saved and newly requested Skyframe keys, including after InputDiscoveryState eviction. Missing inputs and failed nested-set lookups retain per-artifact error handling. TimestampBuilderTest checks that distinct discovered-input sets share a child dep *** RELNOTES: None.
