Incomplete macOS 11+ dyld cache extractor with a focus on Metal-related dylibs.

• Apple: dyld, objc4 (prerequisites)
• Hopper Disassembler: Mach-O inspection, Objective-C struct definitions
• Mach-O Explorer, MachOView: Mach-O inspection
• Wikipedia: LEB128
• Moraea: code, guidance and testing

• copy header and load commands
• copy segments/sections, updating offsets and addresses
• process cache rebase chain
  • generate opcodes
• generate bind opcodes
  • from symbol pointer sections
  • by scanning whole image and resolving external pointers
• generate exports trie
  • regular
  • re-export
  • stub and resolver
• copy symbols, indirect symbols, and string table
• fix Objective-C structures
  • revert selector uniquing
  • revert protocol uniquing
  • fix class, category, and protocol method lists
• mark UUIDs for testing
• produce fully compliant images
  • satisfy install_name_tool -id test
  • satisfy codesign -fs -
  • satisfy dyld_info -objc
  • satisfy Stubber (nm, Objective-C runtime, linker)
  • satisfy lldb
• produce working images
  • work normally with selected images extracted and installed
    • 12.0 DP6 - GeForce bundles
    • 12.5 DP2 - MetalPerformanceShaders and sub-frameworks
    • 12.5 DP3 - QuartzCore, CoreGraphics, Carbon, AppKit
    • 12.5 - AMDMTLBronzeDriver, AMDShared, Metal, MetalPerformanceShaders, MTLCompiler, GPUCompiler
    • 13.0 DP4 - QuartzCore, CoreGraphics, Carbon
    • 13.0 DP4 - AppKit
  • work normally with all images extracted and cache removed
• support Big Sur
• support Monterey
• support Ventura
  • without the __objc_imageinfo hack
• use sane amounts of RAM and CPU
• write automated tests to detect regressions
