Update to Clang 16 for MSVC 2022 support (mono#1724)

* support clang 15.0.7

* Fix Premake archive logic to work with official releases.

* Try and upgrade CI to latest OS versions.

* Try and fix LLD link call in parser.

* CI fixes.

* Enable VS 2019 and VS 2022 for LLVM windows workflow.

* Update to a more recent LLVM revision.

* More build fixes.

* Use the system linker for linking symbols libraries outside Windows.

Builtin lld is giving some weird linking errors when linking with the
new LLVM version. We probably need to set some custom options. Using the
system linker should be a better idea anyway, more robust and future
proof.
