Toolchain: Add support for building the userland with the mold linker

Browse source 
This commit adds support for building the SerenityOS userland with the
new [mold linker].

This is not enabled by default yet; to link using mold, run the
`Toolchain/BuildMold.sh` script to build the latest release of mold, and
set the `ENABLE_MOLD_LINKER` CMake variable to ON. This option relies on
toolchain support that has been added just recently, so you might need
to rebuild your toolchain for mold to work.
