Replace direct access to $wgDisableLangConversion with
LanguageConverterFactory::isConversionDisabled(), and replace direct
access to $wgDisableTitleConversion with
LanguageConverterFactory::isTitleConversionDisabled(). However, most
places that check ::isTitleConversionDisabled() actually want
::isLinkConversionDisabled(), so add that too (and deprecate
isTitleConversionDisabled()).

This change removes a number of spurious dependencies on the global
configuration and reduces code duplication (for example, if the logic
for disabling language conversion were ever to change).
