Target Improvements

[coder137]

• Target states (Build, BuildComplete)
  • Build == TRUE when first build or rebuilt
  • Lock == TRUE after Build is called
• Add LOCK/UNLOCK of usage of functions after Target::Build
  • Some APIs can only be used after build function is called
  • Some APIs should not be used after build function is called
• Check if dependency on Generator is required (revert back to old implementation if required)
• Target Config for defaults
• Add language detection (.asm, .c, .cpp) flags (has_asm, has_c, has_cpp) for compiler specific commands
• Friend classes for private functions
  • CompilePCH
  • CompileObject
  • LinkTarget
• Basic Copy API instead of custom CopyTarget class
  • Copy by Target move
  • Copy by Target const ref
• Target root and build dir customization
• CRTP to add API and Features (https://www.fluentcpp.com/2017/05/16/what-the-crtp-brings-to-code/)
  • Copy API
  • Insert API
  • Source API
  • Header and Include Dir API
  • PCH API
  • Lib Dep and Lib Dir API
  • Flags API
  • Rebuild Deps API
  • Getters and Target Info API
• Append APIs (Similar to Add APIs)
• Target strings
  • Refactor magic strings to constexpr const char * const
• Callbacks for Build customizability
• Custom compile and link arguments with user defined variables similar to Command::AddDefaultArguments
