Fix crash in multi-context D3D11 backend. The crash occured due to a lack of marking a context dirty on eglMakeCurrent(), resulting in a situation where a thread B would call eglMakeCurrent() but before issuing additional GL calls, thread A would issue a draw command. Prior to this change, context state would only be marked dirty on gl calls.
