Lewis Hyatt 3ac6b5cff1 diagnostics: Support for -finput-charset [PR93067]
Adds the logic to handle -finput-charset in layout_get_source_line(), so that
source lines are converted from their input encodings prior to being output by
diagnostics machinery. Also adds the ability to strip a UTF-8 BOM similarly.
