This change modifies the current language by requiring explicit `self` parameter declaration for methods. Methods without `self` parameter in the first position should be treated as statics although that is not yet part of this PR. We add an implicit self to all methods This obviously required updating the whole stdlib and its components, tests etc but the change is pretty straightforward in the diff. Notice that this change **does not** change method dispatch, which was removed in the last changes. This was done on purpose to simplify the implementation for now. We will likely still remove all those implicit selfs to bring true statics. Minor caveat - since `main` doesn't actually need self, already removed that which simplified a lot of code. |

Enso Runtime
The Enso runtime is responsible for the actual execution of Enso code. This means that it encompasses the following functionality:
- Parsing: Taking Enso code as input and generating an AST that maintains a sophisticated set of information about the input.
- Desugaring: Reducing the user-facing Enso code into a simplified language
known as
Core. - Type Inference: Inferring the types of bindings in the user's code.
- Type Checking: Checking that the inferred and provided types for bindings match up across the codebase.
- Optimisation: Static optimisation processes to improve the performance of the user's program.
- Code Execution: Actually running the Enso code.
- Introspection Hooks: Providing hooks into the running code to allow the language server to inspect information about the code as it runs.
Truffle Nodes creation convention
All Truffle nodes that are expected to be created as part of ASTs should
implement a public, static build method for creating an instance. If the node
is DSL generated, the build method should delegate to the autogenerated
create method, so that nodes are always created with build. Such a
convention allows us to easily switch node back and forth between manual and DSL
generated implementations, without the need to change its clients.
The only exception are nodes that are never expected to be a part of an AST –
e.g. root nodes of builtin functions, for which an asFunction method should be
implemented instead.
This convention should be implemented for every node throughout this codebase – if you see one not obeying it – please fix it.
