Emacs: Add new Wayland flavor

[jrm]

Summary

Emacs requires mutually exclusive build parameters depending on
whether the user is running on X11 or Wayland. Rather than require
either set of users to build a custom package, create a new Wayland
flavor.

Test Plan

Test of editors/emacs@wayland: http://pkg.ftfl.ca/data/15amd64-default/2024-04-23_11h31m43s/logs/emacs-wayland-29.3,3.log / http://pkg.ftfl.ca/data/14amd64-default/2024-04-23_14h18m27s/logs/emacs-wayland-29.3,3.log
Test of USES=emacs ports with Wayland flavor: http://pkg.ftfl.ca/build.html?mastername=15amd64-default&build=2024-04-23_14h04m42s

[jrm]

Don't change OPTIONS_DEFAULT here. Do it in a subsequent commit.

[jrm]

Ensure the correct LIB_DEPENDS and USES are specified

[jrm]

There is still a problem to be resolved. Even though we have OPTION_EXCLUDE=CAIRO... for the Wayland flavor, CAIRO_CONFIGURE_WITH=cairo is still adding --without-cairo to CONFIGURE_ARGS.

[jrm]

Add a few more tweaks mostly related to the change in D44929, which this revision depends on.

Restore changes after last arc diff --update

Why not use OPTIONS_SLAVE+=CAIRO? For example:

• Incorporate jbeich's suggestion to use OPTIONS_SLAVE

Thanks updated.

[jrm]

Remove leftover comment

[jrm]

Remove check for wayland flavor; it's no longer necessary with PGTK as a slave option.

[jrm]

Also bump PORTREVISION

[ashish]

Looks good to me.
