Initial `slang-pack` integration (#1974)

* #include an absolute path didn't work - because paths were taken to always be relative.

* First integration of slang-pack.

* Use .os

* Add optional dependency support.

* Update github actions/scripts to update deps. aarch64 needs special handling.

* Upgrade to latest slang-pack for ignore-deps support.

* Fix linux build issues.
