907654a489 [BREAKING] Obsoleting ReflectingExecutor in favor of source gen (#3380)
* Initial working version with tests.

* Updates to validate class data once instead of for each handler method. Also updated Diagnostics Ids to format of MAFGENWF{NUM}

* Formatting and trying to fix generation project pack.

* Another atempt at getting the genrators project to build.

* More attempts to fix generator build and pack.

* Fixing file encodings.

* Initail round of cleanup.

* Trying to fix packing.

* Still trying to fix pipeline pack.

* Remove obsolescence markers, sample updates, and docs from generator branch.

This commit separates the generator core functionality from the
deprecation of ReflectingExecutor. The removed changes will be
re-added in a dependent branch (wf-obsolete-reflector).

* Mark ReflectingExecutor and IMessageHandler as obsolete.

This commit deprecates the reflection-based handler discovery approach
in favor of the new [MessageHandler] attribute with source generation.

Changes:
- Add [Obsolete] to ReflectingExecutor<T>, IMessageHandler<T>, IMessageHandler<T,R>
- Add #pragma to suppress warnings in internal reflection code
- Update Concurrent sample to use new [MessageHandler] pattern
- Add Directory.Build.props for samples to include generator
- Add documentation files explaining the migration
