* Rename template parameter N to InlineBufferCapacity
* Expose InlineBufferCapacity parameter for Set and Map
* Add some comments
* Fixed an error that I introduced recently
Instead of building on top of `BLI::Vector`, just use a raw array
and handle the growing in `BLI::VectorSet`.
After this change, the existing `EdgeSet` can be reimplemented using
`BLI::VectorSet` without performance regressions.
