Deprecate $wgUseAjax in 1.31

This setting was intended to control the legacy AJAX framework, but some
extensions mistakenly used it to control any AJAX functionality at all.

But keeping this around when we're deprecating things like $wgEnableAPI
makes no sense.

[Retro-back-ported after bf61efd87 had landed in 1.32.]
