@update
> [CMakeLists.txt]
  ¦ support extra file installation request (like linker script)
> [boards]
  ¦ [sdl2] indicate that the sdl2.ld file (linker script) should be installed
> [scripts/core/board]
  ¦ support extra file installation indication
  ¦ remove useless toolchain information (handled by the vxSDK)
> [vxsdk.toml]
  ¦ indicate converter asset prefix
  ¦ use the new ENV handling
  ¦ indicate SDL2 linker script
  ¦ indicate SLD2 correct flags information
