Remove webkit-gtk and webkit-gtk-2.0

[jeremyhu (Jeremy Huddleston Sequoia)]

We should remove the old versions of webkit-gtk that were left around for older OS versions that did not have a new enough runtime or toolchain for webkit2.

Currently blocking removal are these ports:

• webkit-sharp (#52399)
• balsa (#52401)
• empathy (#52402)
• evolution-data-server (#52403)
• gnucash (#52404)
• gnucash-devel (#52404)
• liferea (#52405)
• seed (#52406)
• birdfont (#52407)
• gimp2 (#52400)
• gimp2-devel (#52400)
• gimp3-devel (#52400)
• claws-mail (#52408)
• gtkpod (#52409)
• py-webkitgtk (#52410)
• bibledit (#52411)
• midori (#52412)
• uzbl (#52413)

In addition the following GNOME ports that use webkit2-gtk in their current versions fallback to old versions that use webkit-gtk on 10.8 and earier:

• devhelp
• epiphany
• gnome-online-accounts
• yelp

These fallback/compatibility versions would need to be removed from these ports and replaced with portgroup cxx11 1.0.

webkit2-gtk and webkit2-gtk-devel now build on all supported Intel systems, using PortGroup cxx11 1.1.

gnucash: remove peg for webkit-gtk3-2.0

webkit-gtk3 builds on all supported systems
<​http://packages.macports.org/webkit-gtk3>
so no need to peg older webkit-gtk3-2.0 any longer

see: #52398

gtkpod: disable coverweb plugin, dependencies

This plugin wasn't building anyway since after the
change to gtk3 it depends on deprecated webkit-gtk3 rather
than webkit-gtk.

The plugin can be re-enabled if and when it is ever updated
to use webkit2-gtk.

Closes #52409

webkit-sharp: remove outdated port

• no dependents
• depends on deprecated webkit-gtk/webkit-gtk-2.0
• github repo is now archived/readonly

I just updated gnucash to use webkit2; see ​https://trac.macports.org/ticket/52404 and ​https://github.com/macports/macports-ports/pull/8069

I believe the only remaining dependents of webkit-gtk are bibledit and uzbl
