Add autocompleteBraces setting to Behavior configuration

The autocompleteBraces setting existed in CodeEdit's preferences but was never
passed through to the source editor. This adds the setting to the Behavior
configuration struct and conditionally sets up bracket pair filters based on
its value.

When autocompleteBraces is false, both the open pair filters and delete pair
filters are skipped, preventing automatic insertion of closing brackets.

Fixes CodeEditApp/CodeEdit#1691
