[Impeller] Optimize scale translate rectangle transforms (#171841) 
Taken partially from https://github.com/flutter/flutter/pull/170446 with
only the changes to add a ScaleTranslate rectangle transform method
brought over. Unlike the original PR, this PR will apply that optimized
method for any caller who transforms a rectangle rather than just the
matrix/clip tracker for the engine layer tree code.

A benchmark for the new methods is also provided to verify their
improved performance.

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
