build: Remove 'enable' prefix from option names

Meson options are typed, so the prefix isn't necessary, and indeed
looks odd when used to disable the option:
 -Denable_foo=false

Also replace underscores with dashes, which is the preferred meson
style.

build: Stop detecting features automatically

Auto-detect options add some convenience for platforms where a
particular feature isn't available - systemd on non-Linux OS comes
to mind - but the downside is that it is easy to accidentally build
without a desired feature. We consider the latter much more serious
nowadays, so turn our auto-detect options into regular boolean
options.
