sbcl-bootstrap: new package (#46582)

Add pre-built sbcl for x86 and arm for various glibc versions, making
way for an actual sblc built from source.

Also switch to use set_env in a context manager over setting the
environment variable for the build environment. I hit an issue with the
build system due to this in the sbcl package, pre-empting the same issue
here.
