stone-phaser-lv2

Upstream has removed OpenGL support and switched from autoconf to meson.

Some ports needed to be fixed:

audio/fogpad-lv2, audio/ssr-lv2, audio/stone-phaser-lv2,
audio/string-machine-lv2: Add dependency on libGL now that cairo
no longer pulls it in.

devel/doxygen: Add upstream patches to support compressed PDF files
generated by more recent versions of cairo.

www/webkit2-gtk3, www/webkit2-gtk4: Remove requirement for cairo-egl.

x11/hyprpaper: Remove inclusion of unused GLES3 headers so a dependency
on libGLES is not needed.

x11/rofi-file-browser-extended: Fix patch to make sure
GLIB2_INCLUDE_DIRS is defined.
