[release/7.0] Disable EventSource support in NativeAOT by default (#76052)

* Disable EventSource support in NativeAOT by default

`DiagnosticSource` is currently not AOT compatible. If a machine-wide DiagnosticSource-related event listener is enabled (such as PerfView, or possibly even a managed VS debugging session) it activates `DiagnosticSource` code paths within the executable and basically injects a runtime failure into NativeAOT processes due to the AOT-incompatibility of the code.

E.g. trying to do a `HttpClient` web request with PerfView collecting in the background causes a runtime exception to be thrown.

This uses the documented switch to disable `EventSource` support (unless the user specified a different value). Indirectly, it disables `DiagnosticSource` as well.

As a side effect, disabling `EventSource` drops the size of a NativeAOT-compiled Hello World from 3.48 MB to 2.85 MB 🥳.

* Fix tests

* Update Microsoft.Extensions.Hosting.Unit.Tests.csproj

* Cherry-pick relevant parts of #76114

* Port one more test fix
