[Swift] Implements FlatbuffersVector which confirms to RandomAccessCollection (#8752)

Implements FlatbuffersVector which confirms to RandomAccessCollection,
this would give us semi-native sugary syntax to all the arrays in swift port.

This work will also be the foundation of using arrays in swift

* Fix failing tests for Swift
