Remove incomplete battery status/power API

It was initially implemented in #5871 for Godot 3.0, but never really
completed or thoroughly tested for most platforms. It then stayed in
limbo and nobody seems really keen to finish it, so it's better to
remove it in 4.0, and re-add eventually (possibly with a different API)
if there's demand and an implementation confirmed working on all
platforms.

Closes #8770.
