feat(rust_style): Rust-style naming convention rule

[c-antin]

This rule is useful for deno projects that call rust functions via FFI. It attempts to unify naming conventions and enforces declarations and object property names which one creates to be
in UpperCamelCase/PascalCase for classes, types, interfaces,
in snake_case for functions, methods, variables
and in SCREAMING_SNAKE_CASE for static class properties and constants.

See #1322.
