[impellerc] add GLES shader define. (#170375)
Fixes https://github.com/flutter/flutter/issues/169429

For ImageShader.filter we need a way to distinguish between the
coordinate system of GL vs Metal/Vulkan. I documented in
https://github.com/flutter/flutter/pull/169761 how to do it but
neglected to wire up the define. This fixes that.

Flutter Engine

Setting up the Engine development environment

See here

gclient bootstrap

Flutter engine uses gclient to manage dependencies.

If you've already cloned the flutter repository:

  1. Copy one of the engine/scripts/*.gclient to the root folder as .gclient:
    1. Googlers: copy rbe.gclient to enable faster builds with RBE
    2. Everyone else: copy standard.gclient
  2. run gclient sync from the root folder
