Remove special treatment of line drawing characters in libqterminal (bug #42136)

* TerminalView.[cpp,h]: Remove special treatment of line drawing characters. Use
the glyph from the font instead.

* LineFont.h: Remove unused file.

* libgui/qterminal/module.mk: Remove LineFont.h from noinst_HEADERS.
