Revert "Removed superfluous copy in license checker (#167146)" (#167246) 
This reverts commit b4dc23333c286bd6fb9b1aaeea63a933a2d62733.

The license script provides a RegExp wrapper that tracks the cost of the
script's regexes. Dart's RegExp.allMatches returns an Iterable whose
iterators lazily execute the regex. Calling toList will execute the
regex on the entire input within allMatches, allowing measurement of the
regex's cost. Returning the Iterable will instead shift the execution
cost to the caller.

Also, in local measurements I'm seeing significantly better performance
from finding all of the matches immediately with toList versus having
the caller use the lazy iterator.

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
