efl: update to 1.23.1, enlightenment: update to 0.23.1, python3-efl: update to 1.23.0, econnman: update

[q66]

Also, adopt all of these. I'm a core EFL developer, so I can take care of them.

EFL updates

• moved to meson
• reorganized options
• altivec on by default for ppc64, NEON on by default for aarch64
• elogind, drm, wayland support on by default (doesn't break non-elogind scenarios, mostly only for wayland)
• NEON on by default for aarch64, AltiVec on by default for ppc64 (all systems: enableable using the simd option)
• cross-compiling has been tested
• template cleanup and assorted fixes (e.g. elput is built by drm, not elogind, so shuffle the dependencies around correctly)

Enlightenment updates

• mostly just template cleanups/lint fixes

Python-efl updates

• dropped python2 version

Econnman updates:

• moved to a git snapshot (it's had lots of updates since the last release but there also haven't been any changes in ~3 years) - I'll probably spin a new release of that later but first I need to track down the relevant people (which may take a while)
• moved to python3 (only user of python2 efl bindings before this)
• fixed a missing dependency (python3-dbus)
• lint fixes

Other stuff

@mobinmob you are probably interested in this as you did the previous PR. I noticed your previous PR added libcurl as a runtime dependency for E. Any reason for that? Doesn't make much sense to me (E does not use curl anywhere).

Thank you for adopting the packages :)
The libcurl dep was a misunderstanding on my part based on an old email by rasterman.
