Put TraceLoggerFactoryTests into non-parallel collection

[DaveyJonesBitPail]

Description

There is an unstable test https://github.com/ZEISS/czicompress/actions/runs/6969814480/job/18966499474?pr=33 that is presumably caused by running our tests in parallel.

This change will move the TraceLoggerFactoryTests into their own collection with Parallelization disabled. This ought to run the other parallel-capable tests first and then run the TraceLoggerFactory tests sequentially. (see https://xunit.net/docs/running-tests-in-parallel for details)

• TraceLoggerFactoryTests and AppComposerTests have both been added to their own collection.
• External CollectionDefinition classes added for above classes

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

We should probably do the same thing for AppComposerTests which might be the other culprit, here. The page you linked says there must be another test class involved to produce a race condition. And AppcomposerTests also uses a TraceLoggerFactory (via sut).

Afais the proper way to do this is a tad more complicated: see here xunit/xunit#1999 (comment)

I think we could have put them in one NotTheadSafeCollection, but two collections should also be OK
