Yukihiro "Matz" Matsumoto 90c9525fd7 mruby-compiler: refactor lexer to always return cons lists, move variable node generation to grammar actions

Previously the lexer dynamically called new_regx() and new_str() functions
which created different node types based on the var_nodes_enabled flag,
causing complexity in grammar actions and requiring dynamic dispatch handling.

This change simplifies the architecture by:
- Making lexer always return traditional cons structures:
  - tREGEXP: (NODE_REGX . (pattern . (flags . encoding)))
  - tSTRING: (NODE_STR . (string . length))
- Moving variable node generation to grammar actions where it belongs
- Simplifying new_dregx() to always receive traditional cons structures
- Updating mrb_ast_dregx_node to store the whole regx structure

This eliminates dynamic dispatch complexity and centralizes variable node
creation in grammar actions, making the code flow cleaner and more predictable.

mruby-compiler

This mrbgem provides the mruby compiler, which is responsible for parsing Ruby code and generating mruby bytecode.

Functionality

The mruby-compiler gem includes the following components:

Parser: Translates Ruby source code into an abstract syntax tree (AST).
Code Generator: Traverses the AST to produce executable mruby bytecode.
mrbc executable: A command-line tool for compiling .rb files into .mrb bytecode files.

Usage

The mrbc (mruby-bin-mrbc) executable will generate compiled binary from Ruby programs via this gem.

Example of using mrbc:

# Compile a Ruby script to bytecode
bin/mrbc my_script.rb

# Run the compiled script
bin/mruby my_script.mrb
