Make DAC and ProfToEEInterfaceImpl stop using BaseDomain (dotnet#107570)
`BaseDomain` should no longer be needed now that we only have one `AppDomain` and the `SystemDomain` can be treated as separate. This makes the DAC and ProfToEEInterfaceImpl use `AppDomain` directly and check against `SystemDomain::System()` to determine if a pointer is the system domain.
