xtensa: linker: add missing snippets-sections to ace-link.ld

The linker script for intel_adsp ace was missing the
snippets-sections.ld include, causing it to ignore any custom section
defined in with cmake zephyr_linker_sources().

Adding it in the same location as it's done in xtensa-cavs-linker.ld.
