Update VTE when compiler selection updated

[ctreleaven (Craig Treleaven)]

VTE now requires a C++20 compiler, see:

​https://gitlab.gnome.org/GNOME/vte/-/blob/master/meson.build

However, MacPorts base does not support enforcing C++20 as yet. See #64745

Also, I believe that vte should create a 'opt/local/lib/libvte.dylib' in addtion to the versioned libs but does not with vte 0.56.4.

$ ls -l /opt/local/lib/libvte*
-rwxr-xr-x 1 root 423392 Apr  6  2021 /opt/local/lib/libvte-2.91.0.dylib
-rw-r--r-- 1 root 621152 Apr  6  2021 /opt/local/lib/libvte-2.91.a
lrwxr-xr-x 1 root     19 Apr  6  2021 /opt/local/lib/libvte-2.91.dylib -> libvte-2.91.0.dylib

Hopefully the vte update will provide the unversioned library.

Note that vte now uses the meson build system so the existing port will require some mods.

Don't do that. That would make it conflict with the vte-gtk2-compat port.

Port updated to require C++20:

​https://github.com/macports/macports-ports/commit/8d46f6106ff47269b973fc4fe87e8ae0360bdb63

And now uses legacysupport/macports-libcxx, to support 10.12 and earlier:
