[#1762] Implement dumping CST in the compiler

Motivation and Context

Adds a ligo info dump-cst command which is useful for the debugger.

Description

Problem

In the debugger we still use tree-sitter parsers for LIGO contracts. It's not good because we need to update them when LIGO adds/changes something in its syntax. It would be better to get CST directly from the compiler.

Solution

Derive yojson_of functions, convert Yojson.Safe.t into Msgpck.t, and parse it on the adapter's side. Also, strip redundant things like Product and tree-sitter related.
