Add missing `override' (#17098)

This fixes a warning produced by clang:
./tensorflow/core/common_runtime/gpu/gpu_device.h:70:10: warning: 'FillContextMap' overrides a member function but is not marked 'override' [-Winconsistent-missing-override]
  Status FillContextMap(const Graph* graph,
         ^
./tensorflow/core/common_runtime/device.h:124:18: note: overridden virtual function is here
  virtual Status FillContextMap(const Graph* graph,
