Subject: [PATCH] [zephyr] Added Kconfig options to control Matter logs level
 (#13288)

Zephyr logging platform currently uses hardcoded DEBUG log level
and it's not possible to change it through KConfig options.

Added MATTER logging module to Zephyr subsys and enabled setting
Matter logs level using CONFIG_MATTER_LOG_LEVEL option.
