Make firing of ETW events in nativeaot opt-in via the enabled/disabled lib

[elinor-fung]

• Switch the pivot for the enabled/disabled functions to FireEtw* instead of EventPipeWriteEvent*
  • Functions fire both EventPipe and ETW despite the naming (matches coreclr/mono names)
• Moves support for ETW firing (and helpers only used to determine information for tracing) out of the core runtime and into the enabled lib - same opt-in as EventPipe support

The actual implementation still:

• Has separate tracking from that for the EventPipe support
• Uses the .NET Native provider GUIDs (47c3ba0c-77f1-4eb0-8d4d-aef447f16a85, private: 1095638c-8748-4c7a-b39e-baea27b9c589) instead of the normal .NET ones (e13c0d23-ccbc-4e12-931b-d9cc2eee27e4, private: 763FD754-7086-4dfe-95EB-C01A46FAF4CA).

This will enable us to actually reconcile the ETW and EventPipe tracking/contexts/callbacks in nativeaot, which we will need to address #88162 and to switch to the generation scripts based on the event manifest instead of checking in modified parts of the output and manually updating.

I'd also like to move some of the files that are no longer part of the core runtime into a subdirectory (of nativeaot/Runtime) - but in a separate change.

Thanks for making this change! The clean separation is going to make it much easier, both to add new events and for the change to auto-generated python scripts.
