Refactor the class hierarchy for parser states so that
there is a parser state that acts more like a type and
one that acts more like a value (the latter, then, serves
as the base class for the other instantiated parser states).

Fields were not given default values when a struct was declared
without initializers.
Also, cleanup code in the helper function for binary operations
on struct instances.

Compilation interface(s) now contain a compilation context.
The change will make it easier to expand on what each step
of the compilation process needs to know to complete its task
without having to make major changes to the interface.

Do not pass around the MutableTree -- now that we are not
using queries for walking the AST, it is unnecessary.

1. Semicolons were required in the wrong spot.
2. Make semicolons "invisible" (from the tree-sitter perspective).

Refactor into four major components:
1. Common: Things shared among all other components.
2. Lang: P4-language-related components.
3. Runtime: Components required to run a P4 program.
4. Parser: Components for parsing a P4 program from source.
Other components:
1. Macros
2. Tests
3. TreeSitterExtensions: Extra tree sitter functionality

1. Parsing of P4 Parsers was broken: Multiple local elements and
statements were not allowed.
2. Support more functionality on scopes.
3. Refactor variable/identifier.
4. Add more tests.
