Trying to help track down the clipboard issue in mutter#1469 /
gnome-shell#3052 / mutter#1656.

Add meson changes to build a gtk4 variant of libvte, plus
a gtk4 variant of the test application.

Make the minimal code changes required to successfully build
and run on gtk4.

No event handlers yet, and no public API to replace the gtk3
specific APIs.  That will come later.

This should be good enough to get non-terminal users of libvte
started on porting to gtk4.

The text-{modified,inserted,deleted,scrolled} signals are already
documented to be internal and possibly not emitted. Deprecate them
and document them as never emitted; and internally just call the
acccessible object directly instead of via the extraneous signal
emission.

Add API to set how to distribute extra-grid space allocated to the
widget. Previously, vte always positioned the content at the left and top
of the allocation.

For documentation purposes only; won't implement this in vte.

This was already done when receiving one of the known commands; do the
same when receiving an unimplemented command.

Fixes a regression from commit 0136048d.

Unfortunately, this causes a regression in the following simple case:
* Open two instances of a terminal like xfce4-terminal.
* Go to the first instance, copy some string of text, and close it.
* Go to the second instance and paste it. Due to the regression, it won't work.

The cause is that Widget::unrealize calls Terminal::widget_clipboard_data_clear,
this will set m_selection_owned[type] = false. Later when Terminal::~Terminal is
run, the piece of code that calls clipboard_set_text will not be run, because it
depends on m_selection_owned[type] being set (but it ran before on 0.62.3).

This commit moves this last piece of code to Terminal::widget_unrealize, which
is called before setting m_selection_owned[type] = false.

The max_height variable is initialized as 1, and then iteratively
updated to track the maximum height of all the characters from U+0021
to U+007E. The final value is assined to m_height. Hence m_height can
never be zero.

In the case of m_ascent, the contents of m_layout don't change between
the two places where it's assigned. Therefore, the second assignment is
redundant.

Fixes: https://gitlab.gnome.org/GNOME/vte/-/issues/2507

The pango font metrics for some fonts return a height lower than the
height measured from the U+0020..U+007E characters. Using the metrics
in this case may lead to the descenders getting cut off from characters
in the last line, depending on the padding available.

Change the code to only use the pango metrics when its height is at
least that of the measured characters.
