internal/core: allow variable arg functions

This is mostly to allow os-dependent functions
that are convenient, yet still hermetic.

E.g. path.Base(str, path.Unix)

Most of the files in this CL are generated.
Only files not starting with pkg/ and
pkg/internal/builtin.go are relevant.

The basic idea is that to intead of just specifying
the kind of paramter, to also allow a default value.
As this is just a CUE value, this will also allow
for constraints down the line. The old shim
implementation in pkg/internal/builtin.go keeps
it simple, though. Builtins with default values
will have to be hand-coded later on.
