Revert dotnet/runtime#46390 which reverted the Mono parts of dotnet/runtime#46244.

Fixes dotnet/runtime#46389

The issue was that the code in dotnet/runtime#46244 throws in `Thread` constructors before calling `Initialize`.  Which will then cause a finalizer to run on a partially-initialized thread object, which means that `ves_icall_System_Threading_InternalThread_Thread_free_internal` will be called with a null `MonoInternalThread:longlived` field.

* Revert "Partial rollback of #46244 to workaround #46389 (#46390)"

This reverts commit 43d0780.

* [threads] Check for null longlived thread data

This might happen on netcore if the managed Thread constructor throws an
exception before calling InitInternal.  In that case the finalizer may see a
partially initialized object.
