Adding an override to LoggerProvider.GetLogger

[juliuskoval]

Towards #4433
LoggerProvider.GetLogger should accept attributes according to the spec.

Changes

I added an overload to the LoggerProvider.GetLogger method which accepts attributes and I modified the ProtobufOtlpLogSerializer so that it now exports both the version of instrumentation scope and the associated attributes.

Merge requirement checklist

• CONTRIBUTING guidelines followed (license requirements, nullable enabled, static analysis, etc.)
• Unit tests added/updated
• Appropriate CHANGELOG.md files updated for non-trivial changes
• Changes in public API reviewed (if applicable)

If we are going to do this we need to take a copy here so they can't be mutated after being set.

Same idea as here, which also sorts:

I added a benchmark since @Kielek asked me to here. Sorting the instrumentation scope attributes increases the performance impact in the benchmark I added by about 40%, so I'm not sure if it's worth it.
