xtensa: remove unused intel_bdw and intel_byt

[dcpleung]

Both intel_bdw and intel_byt are not being used in upstream Zephyr project. So there is no need to build them.

Quick grep on Zephyr main repo says that these are never used.

Hm... Are there other GitHub workflow files I need to change? CI is still building the removed toolchains even though I removed them from .github/workflows/ci.yml.

Pull request CI uses the workflow from the base branch due to various security reasons. It will work as intended once merged.

@dcpleung was thinking about this the other day and was going to ask if we still needed them :).

[lgirdwood]

Not needed. Can be removed.

@dcpleung There are merge conflicts. Could you rebase?

[lgirdwood]

@dcpleung looks like the GH action will need an update too in order to remove the check for the removed platforms.

[dcpleung]

Rebased. Picolib has GitHub actions on BDW and BYT so those need to be removed too.
