[Courgette] Refactor: Unify Disassembler::Disassemble() and instantiate AssemblyProgram there.

This is part of AssemblyProgram reduction effort. Details:
- Add Disassembler::Disassemble() and dedup separate PE/ELF versions.
  - Instantiate AssemblyProgram there; replaces old behavior where
    caller (program_detector.cc) instantiates and passes as out param.
- Add virtual Disassembler::GetInstructionGenerator().
  - Remove InstructionGenerator's AssemblyProgram* param; update tests.
- Move InstructionReceptor and InstructionGenerator from AssemblyProgram
  to new file instruction_utils.h.
- Rename ParseAbs32Relocs() to ExtractAbs32Locations(); make common.
- Rename ParseRel32Relocs() to ExtractRel32Locations(); make common.
- Make DisassemblerElf32::abs32_locations_ non-mutable.

PTAL, thanks!

courgette/disassembler_elf_32.h:18: #include "courgette/instruction_utils.h"
Including for InstructionGenerator (as side effect we get InstructionReceptor).

instructions parsed from an executable.
InstructionReceptor identical to the code deleted from assembly_program.h.

Compared to old code in assembly_program.h, removed AssemblyProgram* param.
