Most call sites for transitions will only apply transitions to one or two
resources, and don't need to use the bo set, where each call is guaranteed
to insert the bo, only to walk the set immediately afterwards. Instead, they
can just append the barriers to the dynarray directly and skip the bo set.
Draws and dispatches still use the append approach, to accumulate the full
set of state needed for each subresource for the case where a single
[sub]resource is bound to the pipeline in multiple places.
