xtensa: add intel_tgl_adsp

This adds the config and overlay to build the toolchain for
the audio DSP on Intel Tiger Lake SoC, which is used by
the intel_adsp_cavs25 board in Zephyr main.

The overlay archive is from branch sof-gcc10.2,
commit 726dd0c8786c2e41c109b3d4bc3ce8edfd6e1b6b at
https://github.com/thesofproject/xtensa-overlay, file
xtensa_lx7hifi4.tar.gz.
