Move ServerCertificateCustomValidationCallback [Ignore] out of this PR

The [Ignore] for the crashing AndroidMessageHandlerTests
.ServerCertificateCustomValidationCallback_* tests (dotnet#8608)
belongs with the trimmable-typemap work; move it to dotnet#11801. This PR is
now scoped to the MTP streaming-results change only.
