[nrf fromtree] openthread: fix logging configuration

Currently, `CONFIG_OPENTHREAD_LOG_LEVEL` is used to set log level
in OT and register log modules in Zephyr. OpenThread allows 5
levels, causing issues when `OPENTHREAD_LOG_LEVEL_DEBG` is
selected ad we are trying to register modules with unknown lvl.

This commit adds `CONFIG_OPENTHREAD_MODULE_LOG_LEVEL` which is
aligned for Zephyr's log levels.
