Review comment:
Rather than opting out of dependencies, would it make more sense to have
an `ARROW_COMPUTE_STRINGS` (feel free to pick a better name) feature flag that,
if enabled, requires utf8proc and re2? Unlike the compression libraries that
have the `ARROW_WITH_X` flags, these dependencies are tied to specific
functionality that can't really exist without them, right?
