SerialConnect: allow to change line terminator

* It can now be used to send AT commands for example, which need \r
instead of \n.

SerialConnect: draw the cursor.

* Drawn as "inverse video" for now.
* Should use VTerm state to get the cursor shape (rect, underline or
left line)
* Should also handle blinking if enabled, and visibility.

SerialConnect: use ints for font metrics

As pointed by Ingo, using a float here is useless because we want each
line to be the same integer number of pixels. Now thigs are drawn
properly and the view has the exact same size as Terminal's one (tested
with font sizes 10 and 18, so different leading values don't seem to be
a problem).

Thanks for reviewing!

SerialConnect: implement scrollback.

Handle colors.

Resize terminal buffer with window.

Unlike in Haiku terminal, vterm does not rearrange lines wen they
are wrapped. Chars outside the viewing area are just lost.

Working serial connection.
Still need some work on displaying the right chars at the right place.

WIP version of SerialConnect. Not working, but added to the tree anyway so :
* You can code review it
* You can help developping
Uses libvterm as the backend for parsing ANSI escape sequences. The lib was
changed slightly to build with GCC2. It could be used by Terminal as well as
it seems cleaner and more reliable than our current parser.
