memctx: allow the metadataonlyctx thats reusing the manifest node
When we have a lot of files writing a new manifest revision can be expensive.
This commit adds a possibility for memctx to reuse a manifest from a different
commit. This can be beneficial for commands that are creating metadata changes
without any actual files changed like "hg metaedit" in evolve extension.
I will send the change for evolve that leverages this once this is accepted.
