Abtin Keshavarzian cb4b28313b [logging] add support for per-instance log levels (#12740) 
This commit introduces the ability to set and manage log levels on a
per-instance basis when dynamic logging is enabled, while maintaining
backward compatibility with existing logging behaviors.

The existing `otLoggingGetLevel()` and `otLoggingSetLevel()` APIs are
repurposed to manage the "global" log level. They continue to behave
exactly as before in both single-instance and multi-instance
configurations, ensuring that existing users of these APIs do not need
to change their implementations. To provide more granular control, new
APIs `otGetLogLevel()` and `otSetLogLevel()` are added to handle
per-instance log levels.

Specifically, this commit makes the following changes:
- Adds `mLogLevel` to `Instance` to track the instance-specific log
  level.
- Renames the global log level static variable to `sGlobalLogLevel` and
  introduces `GetGlobalLogLevel()` and `SetGlobalLogLevel()` to manage
  it in a multi-instance configuration.
- Updates `otGetLogLevel()` and `otSetLogLevel()` APIs to handle
  per-instance log level retrieval and configuration. If a specific
  level is not set for an instance, it falls back to the global
  log level.
- Adds `mIsLogLevelSet` to distinguish between an explicitly set
  instance log level and the global fallback in multi-instance builds.
- Introduces `otPlatLogHandleLogLevelChanged()` platform callback to
  notify the platform when an instance-specific log level is updated.
- Updates Nexus tests to use `SetGlobalLogLevel()` instead of the
  deprecated instance `SetLogLevel()` method.
