Add C code generation backend (#68)
* [cbackend] Adds an AST for C

This should cover enough C to implement the microjuvix backend.

* [cbackend] Add C serializer using language-c library

We may decide to write our own serializer for the C AST but this
demonstrates that the C AST is sufficient at least.

* [cbackend] Declarations will always be typed

* [cbackend] Add CPP support to AST

* [cbackend] Rename some names for clarity

* [cbackend] Add translation of InductiveDef to C

* [cbackend] Add CLI for C backend

* [cbackend] Add stdbool.h to file header

* [cbackend] Allow Cpp and Verbatim code inline

* [cbackend] Add a newline after printing C

* [cbackend] Support foreign blocks

* [cbackend] Add support for axioms

* [cbackend] Remove code examples

* [cbackend] wip FunctionDef including Expressions

* [parser] Support esacping '}' inside a foreign block

* [cbackend] Add support for patterns in functions

* [cbackend] Add foreign C support to HelloWorld.mjuvix

* hlint fixes

* More hlint fixes not picked up by pre-commit

* [cbackend] Remove CompileStatement from MonoJuvix

* [cbackend] Add support for compile blocks

* [cbackend] Move compileInfo extraction to MonoJuvixResult

* [minihaskell] Fix compile block support

* [chore] Remove ununsed isBackendSupported function

* [chore] Remove unused imports

* [cbackend] Use a Reader for pattern bindings

* [cbackend] Fix compiler warnings

* [cbackend] Add support for nested patterns

* [cbackend] Use functions to instantiate argument names

* [cbackend] Add non-exhaustive pattern error message

* [cbackend] Adds test for c to WASM compile and execution

* [cbackend] Add links to test dependencies in quickstart

* [cbackend] Add test with inductive types and patterns

* [cbackend] Fix indentation

* [cbackend] Remove ExpressionTyped case

https://github.com/heliaxdev/minijuvix/issues/79

* [lexer] Fix lexing of \ inside a foreign block

* [cbackend] PR review fixes

* [chore] Remove unused import

* [cbackend] Rename CJuvix to MiniC

* [cbackend] Rename MonoJuvixToC to MonoJuvixToMiniC

* [cbackend] Add test for polymorphic function

* [cbackend] Add module for string literals
