Localized Chromoting Host on Mac and Linux.

Re-landing r213997. TBR because this is a trivial, mechanical fix.

This CL implements generation of localizable strings from remoting_strings.grd file. Depending on the platform the localized resources are placed to:
- Mac: localized .string and .pak resources are added to each application bundle under 'Resources/<locale>.lproj'
- Linux: localized .pak files are placed under 'remoting_locales' directory next to the binary locading them.
- Windows: .rc resources are generated from .jinja2 templates and embedded into a relevant binary.

Chrome l10n and i18n APIs are used to retrieve the current locale and RTL flag (Mac & Linux). The it2me plugin sets the locale to match the locale of the browser.

Collateral changes:
- UiString is not used any more.
- Increased width of disconnect window message on Mac.
- The host plugin version is correctly reported on Mac.
- Dialogs use RTL templates in case of RTL languages. No more updating the templates dynamically (Windows).
- remoting_unittests.ResourcesTest now runs on Mac, LInux and Windows.
- '@' is used for variable substitutions by remoting_localize.py.
- HOST_PLUGIN_MIME_TYPE is defined in one place now.
- Deleted unused commong_resources.grd.

Mac installer and preference panel are not localized yet.
