Title: Bug 748086 - Factors out usages of synchronous XHR requests

- Introduced api-utils/url/io module
- Added docs and unit test
- Updated modules to use the new modules (except tab-browser because is going to be deprecated)
- Deprecated require("api-utils/utils/data").getChromeURIContent, left for internal uses.
- Replaced console.warn with console.error for deprecated functions in data.js (see bug 785826)
- Fixed testcfx adding new modules dependecies

This is the fixed version for `cfx testcfx` of pull #542. The only difference is the code committed for `python-lib/cuddlefish/tests/test_xpi.py`.
