Yukihiro "Matz" Matsumoto 392f4fabc0 mruby-compiler: use variable-sized ast nodes for call, array, and hash

Introduces variable-sized AST nodes for method calls (NODE_CALL),
arrays (NODE_ARRAY), and hashes (NODE_HASH). This change improves
memory efficiency by storing elements directly within the AST node,
avoiding an extra layer of pointer indirection for their data.

This is achieved by adding new data structures and functions in both
the parser and the code generator to handle these new node types.
Variable-sized nodes are now enabled by default.

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
