Save remote output metadata to ActionCache and load them before checking action cache This PR extends `ActionCache.Entry` to store output metadata by having a map of <Path, Metadata>. This map is updated after action execution when we update action cache so that metadata of all outputs of the action are saved. Before checking the action cache (when executing actions), we will load the output metadata into output store if it is remote and the correspondingly local one is missing. With this change, remote output metadata is saved to disk so build without bytes can use them among server restarts. We can also download outputs after action execution since remote output metadata can be accessed outside. Part of https://github.com/bazelbuild/bazel/issues/12665. Fixes https://github.com/bazelbuild/bazel/issues/8248. Closes #13604. PiperOrigin-RevId: 388586691
