cc: Delete ContextProvider::MakeGrContextCurrent.

It is not necessary to explicitly make the GrContext current.
The underlying GL context is automatically made current via a
callback setup by all implementations of cc::ContextProvider.
Ganesh calls this callback before issuing any GL command, which
ensures the the appropriate GL context is current.
