[Chromoting] Enable jscompile for AppRemoting's feedback_consent page.

[Chromoting] Enable jscompile for AppRemoting's feedback_consent page.

The cl does 4 things:
(1) Adds a list (in gyp) for the feedback_consent js files.
(2) Uses build-html.py to build feedback_consent.html from a template.
(3) Adds an action to run jscompile over the feedback_consent js files.
(4) Fixes the errors/warnings reported by jscompile.
