Add an intermediate instruction set

This intermediate representation or instruction set should support the scripting features from multiple RAGE games (at least, GTA IV, MP3, GTA V and RDR3) so it can be converted to and from the real scripts bytecode.

It should also be simpler where possible, for example:

  • Instead of all PUSH_CONST_* for integers or floats just a single opcode for integers and another for floats.
  • No *_LOAD or *_STORE versions of other opcodes. Use the LOAD and STORE opcodes after pushing the address instead.
  • Instead of versions of the same opcode with different operand size like STATIC_U8 and STATIC_U16 just a single opcode.

For now, the intermediate instruction set will only support the decompiler.
For the compiler, an abstraction over CodeGenerator with specific implementations for each game should work.
