compliance: Revert "scripts: handle auto defined ZEPHYR_<name>_MODULE"

With the requirement in #78316 for Zephyr modules to always define
ZEPHYR_<name>_MODULE Kconfig setting then there is no longer a need
for this commit. Simplify check_compliance by reverting ths commit.

This reverts commit 35e28e63.
