Add VbExGetLocalizationCount

Browse Source 
VbExGetLocalizationCount is a callback function which is supposed to
return the number of screen locales supported by VbExDisplayScreen.

After this change, we still try to get the number of locales from GBB
first but when it fails, VbExGetLocalizationCount is called. The error
code from VbGbbReadBmpHeader will be masked, similarly to the error from
VbDislayScreenFromGBB.
