A protocol defines a blueprint of methods, properties, and other requirements that suit a particular task or piece of functionality. The protocol can then be adopted by a class, structure, or enumeration to provide an actual implementation of those requirements. Any type that satisfies the requirements of a protocol is said to conform to that protocol.
This pull request adds support for parsing protocols by achieving the following:
Adding support for parsing basic protocols
Adding parsing support for optional methods and properties
Adding parsing support for conformed protocols (protocols that the given protocol inherits)
Adding support for custom types in protocols via associatedTypes
Adding support for methods and properties that act as default initialisations for protocols

Extension support (#1815) might need to be added to implement default initialisation functionality
If there's a detail of this PR that will require a whole lot of extra effort to implement, just file a bug (or comment on an existing bug) and leave a TODO in the code to finish that work later. You don't have to do the whole feature in one PR. This means you can land your PRs quicker, and it also makes them easier for me to review because the individual PRs will be smaller and simpler.
