rust: kbuild: introduce `core-flags` and `core-skip_flags`
In the next commits we are introducing `*-{cfgs,skip_flags,flags}`
variables for other crates.
Thus do so here for `core`, which simplifies a bit the `Makefile`
(including the next commit) and makes it more consistent.
This means we stop passing `-Wrustdoc::unescaped_backticks` to `rustc`
and `-Wunreachable_pub` to `rustdoc`, i.e. we skip more, which is fine
since it shouldn't have an effect.
In addition, use `:=` for `core-cfgs` to make it consistent with the
upcoming additions.
