treewide: make more settings conditionally available

Browse Source 
Some settings only make sense on particular platforms, or only when a certain
experimental feature is enabled. Several of those were already conditionally
available. Do the same for a bunch more instead of silently ignoring them.
Exceptionally, the use-case-hack setting is not made conditional because it is
included in the test suite.
