GUI: U32: Improve u32 in all engine subsystems

- Common: add wordWrap function to ustr.cpp
- Bladerunner: Explicitly state we have a U32String in subs (same as Subtitles::loadOuttakeSubsText)
- Don't use translations for engine specific "put strings", because they might not support.
- SCI: Use const references for showScummVMDialog
- SCUMM:
-- Don't use translation in md5 warning. left comments with the translated version.
-- Remove some redundant headers in help.cpp
-- Don't use translation in handleSaveload when printing to console
-- Also, display success transaction correctly via u32::format
- TESTBED: Use fake constructor when setting label of button
- SKY: Correctly use translation when using SaveStateDescription
- ULTIMA: Don't use translations when display_string
- ENGINES:
-- GenerateUnknownGameReport correctly, with proper translations.
-- There was an error, where a function had been declared twice, in a header file. Correct this.
