Remove Battery Status API from the tree

Because it's a privacy (tracking and fingerprinting) risk (https://blog.lukaszolejnik.com/battery-status-readout-as-a-privacy-risk/) Apple never enabled it on their ports.

Mozilla tried to fix it (https://bugzilla.mozilla.org/show_bug.cgi?id=1124127), and then Mozilla decided it wasn't worth keeping around for web content (https://bugzilla.mozilla.org/show_bug.cgi?id=1313580)

The Linux port maintainers don't see a reason to keep it around, as discussed in this thread - https://lists.webkit.org/pipermail/webkit-dev/2016-October/028468.html

I'll use this bug to remove it in a few days as long as the thread continues to have no objections.

We should wait a few days to do this to give people a fair chance to voice objections.

There's no rush.
