Pull request description:

  This switches us to using a [LLD](https://lld.llvm.org/) based toolchain for macOS builds.

  ### Benefits
  * Less complicated macOS toolchain.
  * No longer beholden to Apple releasing it's [source](https://opensource.apple.com/source/) for [cctools](https://opensource.apple.com/source/cctools/), [ld64](https://opensource.apple.com/source/ld64/) & [libtapi](https://opensource.apple.com/source/tapi/).
  * No more reliance on third parties to modify those sources for us. i.e [apple-libtapi](https://github.com/tpoechtrager/apple-libtapi), [cctools-port](https://github.com/tpoechtrager/cctools-port) (cctools + ld64).
