  Reland "Not recreate Framebuffer for eglMakeCurrent() call"
  
  This is a reland of commit bf9c815263455403e587a9d2b0fdb9fb8e964208
  
  Original change's description:
  > Not recreate Framebuffer for eglMakeCurrent() call
  >
  > Right now, in eglMakeCurrent() call, ANGLE always release the
  > default framebuffer object associated to the current context,
  > and create a new default framebuffer object for the new current
  > context. It impacts chrome performance, since chrome call
  > eglMakeCurrent() a lot. With this CL, the default framebuffer
  > will be created with gl::Context. When the surface is changed
  > by eglMakeCurrent() call, ANGLE will detach the previous surface
  > from the associated framebuffer, and attach the new surface to
  > the next current context's default framebuffer.
