Update platform views documentation with 4 standard names and abbreviations (#167752)
After talking with @gmackall we are going to try to standardize on 

Virtual Display (VD) 
Hybrid Composition (HC) 
Texture Layer Hybrid Composition (TLHC)
Hybrid Composition++ (HCPP) 

for our documentation covering android platform views and how we
describe the code to each other.

For example HC++ would be discouraged, so would referring to HC as
expensive.

This pr also removes TargetSdk since that annotation has been deprecated
for a number of years and can be wholly replaced by the already used
RequiresApi annotations.

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
