Migrate more prints to font::, determine font for most textboxes

Some textboxes need to be in the level font (like room names, cutscene
dialogue, etc - even in the main game), and some need to be in the
interface font (like when you collect a shiny trinket or crewmate). So
most of these textboxes now have graphics.textboxprintflags(font_flag)
as appropriate.

RoomnameTranslator.cpp is now also migrated to the new print system -
in room name translator mode, the room name is now displayed in the 8x8
font if it's untranslated and the level font if it is.
