Enable chrome.gyp:browser on iOS

Enable chrome.gyp:browser on iOS

When unit_tests was turned down on iOS, no chrome.gyp target was added
to replace it in all.gyp, so nothing has been exercising that part of
the build system on iOS.

This adds 'browser', and fixes issues that have crept in since then.
Most notably:
- Removes chrome_browser_non_android_sources, moving everything that
  was there to ..._non_mobile_sources
- Removes an iOS-only class that was removed downstream, and had
  rotted upstream.

This won't find link issues, but will at least ensure that the gyp
files continue working on iOS for as long as they are necessary.

Doh!

It took me a little while to figure out why non_android_sources wasn't breaking
iOS upstream.

The diff here looks weird because it shows as a move of everything between
non_android and non_mobile up, since non_android had far more sources so
anchored the diff.

In practice what I did was move everything in non_android into non_mobile, and
then sort that whole list.

Thanks, this was a helpful comment.
