Protection Key is not removed during tenant removal

[MikeAlhayek]

Describe the bug

When we remove a tenant using the UI, the database and the host container are cleared of the tenant. But the Protection key is not removed.

Orchard Core version

Add the version of the Orchard Core NuGet packages you use, or the commit hash if you can reproduce this with the source code.

To Reproduce

Steps to reproduce the behavior:

1. Create a tenant
2. Set it up
3. Disable it
4. Remove it
5. Check the protection key DataProtectionKeys.xml it will exists. I tested this when data protection are stored in Azure Blob storage "not sure if locally we have the same problem".

Expected behavior

I would expect everything related to the tenant being removed to be removed.

Same solution as the related issue, create an IShellRemovingHandler to handle it. And for any data protection provider.
