Maintain current cuda context in CUDADriver by checking against a threadlocal
that stores the id of the current context, and doesn't clear the context when
the root scope is popped. On a single context case, this saves all context
setting and getting cuda calls.
Note that the verification that the current context has not been modified
around us is removed. A debug option (kVerifyCudaContext) has been added that
can be turned on to help debug those cases.
