Disable bidi bracket matching unless enabled via ASS_Feature
Bracket matching is incompatible with VSFilter (even on modern
Windows), so disable it by default. But as it's generally
a good thing (and 100% more compliant with current Unicode),
keep it available as an ASS_Feature.
It can be toggled individually or enabled as part of the
catch-all ASS_FEATURE_INCOMPATIBLE_EXTENSIONS feature.
If libass is compiled against FriBidi older than 1.0,
bracket matching is impossible. Signal this at runtime
by failing to recognize the ASS_FEATURE_BIDI_BRACKETS
feature. This way, clients who want to use bracket matching
can set the feature without any compile-time checks for
FriBidi and can be freely linked against libass that is itself
compiled against any version of FriBidi; and yet they can
detect at runtime whether the feature is actually enabled.
