Part of #99298

This will require bringing up a basic data stream reader and registering enough data types and instances in the runtime so that we can get at the exception.

Additionally see sos_printexception_walkthrough.md#exception-informaiton for a walkthrough of the relationship of these interfaces to what SOS is doing

For CLRMA, we will need a few additional methods:

.NET 9

We maintain a branch feature/9.0-cdac-backports that has selected data descriptor and contract changes necessary for the cdacreader to interrogate a net9.0 runtime. The backports to this branch include:

• [feature/9.0-cdac-backports] Data descriptor changes for GetMethodDescName #106463.
  Replaces [cdac][.NET9] Data descriptor changes for GetMethodDescData #106417
