  Vulkan: Add command option to run app traces with minimum GPU work
  
  This CL interposes the draw call API entries. If enabled by command line
  option "--minimize-gpu-work", it will override all draw calls to render
  a single GL_POINT instead. It forces view port and scissor size to 1x1.
  It forces all data copy to 1 texel or 1 byte. It ignores
  glGenerateMipmap call. The goal is to make the frame time reflect the
  driver CPU performance as much as possible so that we can use it to
  compare ANGLE vs native GLES on the driver overhead, as well as
  identifying CPU hot spot.
