SDK global debug mode configuration

Re #664 (comment)
Relates to #597

Eg:

Log(tag, level, message, args)

You can configure the minLevel for filtering such as error during SDK init.

debugConfig {
	enabled: false,
    minLevel: error
}

We'd call Log.log('DiskBufferingConfiguration', ErrorLevel.Error, 'The error is: %s', error) and this will call Logcat internally.
If enabled is enabled and if ErrorLevel is >= minLevel, we'd call logcat, otherwise not.

This most likely has to live in the OTel Java SDK (core) since many Log calls would live there.
