Missing log function in Zephyr standalone platform (project-chip#34413)

* Add missing log option

Signed-off-by: Caldeira, Quentin <QuentinCaldeira@eaton.com>

* Add missing logging Kconfig

I've created this one with the previous PR, but I didn't see that it was ignored by .gitignore because
I named it Kconfig.log, so rename it to Kconfig.logging

Always with the purpose to separate each function in a dedicated Kconfig to source in your application, to avoid
Kconfig warning, and let your prj.conf be application configuration only

* Move CHIP_APP_LOG_LEVEL

Because every zephyr's user seems to rely on the zephyr logging system, move the log declaration into the zephyr
folder
