build: remove XTOS-specific sections from cmake lists

The "is_zephyr()" macro is used to fork sections of cmake lists for
Zephyr and other builds. Remove XTOS-specific sections but keep
non-Zephyr host-based builds like testbench, plugin and cmocka. Also
use a more logical "is_zephyr(zephyr)" form instead of the earlier
"is_zephyr(it_is)."
