Implement the AndroidChipLogging (#34899)

* Refine android log priority based on category

This change adds ANDROID_LOG_INFO priority for kLogCategory_Progress.
Refine android log priorities to enhance debugging efficiency and
prepare an environment where lower-priority logs can be controlled and
excluded using the log filter function.

* Implement the AndroidChipLogging

Implemented the AndroidChipLogging.setLogFilter to enhance the logging
mechanism. This method allows for the filtering out of unnecessary or
redundant log messages, significantly reducing noise in the logs.
To use the log filter, call AndroidChipLogging.setLogFilter with the
appropriate filter criteria. The arg is log level in android.util.Log.
Example: AndroidChipLogging.setLogFilter(android.util.Log.ERROR)
