With this change, all reproducible repository rules can now be cached in a disk or remote cache, including those with dependencies recorded dynamically during evaluation. This is made possible by introducing a new intermediate type of synthetic AC entries. When looking up the predeclared inputs hash for a repo rule with dynamic dependencies, the action result for such an intermediate entry lists one or more sets of inputs (e.g. a particular file in another repo or an environment variable name). These inputs are then requested from Skyframe and their current values are hashed to obtain the key of the next AC entry, which is again either an intermediate entry or a final entry containing the contents of the repository. RELNOTES: The remote repo contents cache now supports all reproducible repo rules. Closes bazelbuild#27634.
