Add SetMinimumWidth to Menu2 for chromeos. Removed LanguageSwitchModel::GetFirstLevelMenuWidth

Add SetMinimumWidth to Menu2 for chromeos. 
This is to remove gtk dependency from menu2 code in chromeos and to make DOMUI transition smooth (crosbug.com/6497) 

Removed LanguageSwitchModel::GetFirstLevelMenuWidth as this does not seem to be used by anyone.

BUG=none
TEST=none

Ben this the version w/o ifdef macros.

Denis, is it okay to remove LanguageSwitchModel::GetFirstLevelMenuWidth()?
Looks like it's not used anywhere.
