Record logger name as the instrumentation scope name

[sfc-gh-jopel]

Description

(Copied from #3810)

Fixes issue #2485 Record logger name as the instrumentation scope name

Approach: Cache one Logger object per Python logger (name, version, schema_url) in LoggingHandler.

The Open Telemetry Spec specifies that the Logger Name SHOULD be recorded as the Instrumentation Scope name. Reference: open-telemetry/opentelemetry-specification#2359

This has already been implemented in Open Telemetry Java, but not in Open Telemetry Python.
