[Ameba] Dynamic logging (project-chip#25273)

* [logging] dynamic log level setting

* [logging] cleaup

* [logging] use enums instead of macros

* [logging] cleanup

* [logging] change loglevel to enum class
- change namespace

* [logging] use to_underlying
- change enum class name

* [logging] fix compile errors
- change back the namespace to chip::Logging::Platform
