x11-misc/sddm: add 0.20.0

See also:
https://github.com/sddm/sddm/releases/tag/v0.20.0

This is adding back RDEPEND=x11-base/xorg-server for two reasons:
- X11 is the default DisplayServer, with all other options EXPERIMENTAL
- every other distro still depends on it, probably for that reason

+Subject: [PATCH] Session: Parse .desktop files manually again
+
+Using QSettings::IniFormat doesn't quite work. Implement a custom parser
+for those files to handle them according to the specification.

+Fixes #1745
