Description
Adding, updating or deleting a managed resource during Hot Reload/EnC currently requires restarting the application. To avoid that we need the runtime to allow changes to ManifestResource table.
Embedded resources listed in the ManifestResource table are stored in the resource section of the PE file, at an offset stored in the ManifestResource table. Similarly to FieldRVA implementation, we can store the blob in the IL delta stream in EnC delta and interpret the offset as a position in the IL stream.
Once implemented a new EnC capability ChangeManifestResources should be added.
The resource string cache also needs to be invalidated when Hot Reload change is applied: #115911
The following APIs should return the updated resources after change is applied:

https://learn.microsoft.com/en-us/dotnet/api/system.reflection.assembly.getmanifestresourcenames?view=net-9.0
https://learn.microsoft.com/en-us/dotnet/api/system.reflection.assembly.getmanifestresourcestream?view=net-9.0
Any Reflection caches that store the data need to be invalidated on Hot Reload update.
Reproduction Steps
Update .resx file during Hot Reload/EnC session.
Expected behavior
The change is applied without restarting application.
Actual behavior
The change is ignored.
