xtensa: add xtensa-intel_ace40_zephyr-elf

This adds the config and overlay files to enable building
the toolchain needed for the intel_adsp/ace40* boards
in Zephyr.

In the GitHub workflow, it adds the entry for Zephyr board
but disabled for now as a copy of ACE30. Will need to revisit
both later.
