infra: use LLD for all configurations
This makes it consistent to use LLD across all configurations. It also moves away from using gold linker, which has recently been deprecated.
On top of that LLD is faster and has better compatibility with LLVM toolchain that is already used for building.
This commit also fixes warnings that can sometimes occur with BFD linker that doesn't fully support DWARF 5, at least the version on the builder: DWARF: invalid or unhandled FORM value: 0x22
Some projects already replaced linker in thier build scripts for this reason.

Added missing -Wno-unused-command-line-argument, should fix most failures.
Are we using lld by default? I'm not sure we are, but I haven't looked.

The proposal is to use LLD by default. I've outlined the main reason in commit message. Currently BFD linker is used, with some jobs using GOLD. Idea is to unify and modernize to use LLD.
