Clean up third_party/cld.

1. Remove files we don't use that come from toolbar
2. Simplify the directory structure by removing the redundant
intermediary directories bar/toolbar/cld/i18n

This will bring CLD a step closer to where it can be open-sourced separately (or along with CED for encoding detection.). It's not there yet.


In addition to the clean-up, change |LanguageCode*| return 
'nb', 'he', 'fil' instead of 'no', 'iw', and 'tl'. 

Also, use LanguageCodeWithDialects instead of LanguageCode to get 'zh-CN' 
instead of 'zh'. This is to simplify the 3-way mapping between 
Chrome's UI locale code, CLD's language code and what's accepted by 
Google Translate. It's also another preparation for open-sourcing because
we'd better use the standard code rather than the obsolete code like 'iw'
when open-sourcing.

BUG=32759, 33613
TEST=third_party/cld builds on all platforms and pass the following tests:
- unit_tests: Extension*.DetectTabLanguage and CompactLangDetTest.* 
- browser_tests: ExtensionBrowserTest.Toolstrip
