  Reland "Define and expose EGL_ANGLE_power_preference extension."
  
  This is a reland of ac58e63295f093b7518535bdd060ff832025b0c5
  
  The original CL was reverted in a rush because I thought there was an
  uninitialized variable bug, but upon later re-review this turned out to
  not be the case.
  
  Original change's description:
  > Define and expose EGL_ANGLE_power_preference extension.
  >
  > Allows application to select the integrated or discrete GPU on
  > dual-GPU macOS systems.
  >
  > Tested by modifying the example program at:
  > https://github.com/grorg/ANGLEIOSurfaceTest
  >
  > and verifying that both integrated and discrete GPUs can be selected.
  > (The changes to that program will be upstreamed once some build issues
  > are resolved.)
  >
