Add Execution Context control to Text.write (#6459) 
- Adjusted `Context.is_enabled` to support default argument (moved built in so can have defaults).
- Made `environment` case-insensitive.
- Bug fix for play button.
- Short hand to execute within an enabled context.
- Forbid file writing if the Output context is disabled with a `Forbidden_Operation` error.
- Add temporary file support via `File.create_temporary_file` which is deleted on exit of JVM.
- Execution Context first pass in `Text.write`.
- Added dry run warning.
- Writes to a temporary file if disabled.
- Created a `DryRunFileManager` which will create and manage the temporary files.
- Added `format` dropdown to `File.read` and `Data.read`.
- Renamed `JSON_File` to `JSON_Format` to be consistent.

(still to unit test).

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.
