Cluster Manifest Broken by v7.2.5

We experienced an issue where after bumping from `v7.2.4` to `v7.2.6` we were getting from following logs from our remote cluster:

> Exception reading message "Request [ sys.client/97a1e507408e496e91dda84405325844]->[S10.16.5.43:30004:0 sys.svc.manifest/10.16.5.43:30004@0] #1" from remote endpoint "10.16.5.48:52438" to local endpoint "10.16.5.43:30004"

With the following exception:

Followed by the following log from our client host:

> Failed to fetch cluster manifest update from "GrainReference:sys.svc.manifest/10.16.5.43:30004@0:Orleans.Runtime.IClusterManifestSystemTarget".

These logs occur every minute, on every attempt to retrieve cluster manifest.

We managed to fix this by downgrading all of our Orleans references to `v7.2.4`. We noticed that there was some kind of change related to the cluster manifest in the [v7.2.5 release](https://github.com/dotnet/orleans/releases/tag/v7.2.5) that might be related?

Start by reproducing the v7.2.4-to-v7.2.6 upgrade and trace the cluster-manifest request from Orleans.Runtime.Messaging.MessageSerializer into TypeConverter.ResolveCompoundAliasType. Read TypeConverter.cs, RuntimeTypeNameRewriter.cs, and the v7.2.5 release notes for the manifest change. Done means upgraded hosts can fetch manifest updates without the TypeLoadException.
