Switch lots of callers to using nsLayoutUtils::GetFontMetricsForFrame and nsLayoutUtils::GetFontMetricsForStyleContext. (Bug 678671, patch 1) r=roc

Browse Source 
This changes a number of callers that were previously bypassing the use
of the correct language (with either no language or the charset-detected
language on the pres context via nsPresContext::GetMetricsFor) and/or
the correct user font set to pass the correct values, which should
improve the correctness of the behavior of whatever they were using the
fonts for, and also reduce the number of unique sets of font metrics
requested (which helps nsFontCache effectiveness).
