Subject: Rename Crossgen2 dependency graph ETW event source (#37731)
X-Git-Tag: submit/tizen/20210909.063632~7444
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c78f333834dd4ad997c374a64243e8336eca5765;p=platform%2Fupstream%2Fdotnet%2Fruntime.git

Rename Crossgen2 dependency graph ETW event source (#37731)

When crossgen2 is run with `Microsoft-ILCompiler-Perf` provider enabled, events are not named properly in PerfView (`Microsoft-ILCompiler-Perf/EventID(1)` instead of `Compilation/Start`) and an error event indicating multiple EventSource instances with the same GUID are enabled:
```
    ERROR: Exception in Command Processing for EventSource Microsoft-ILCompiler-Perf: An instance of EventSource with Guid 607164a4-cacb-5f22-92fb-62a11541e285 already exists.
```

Name the dependency analysis EventSource `Microsoft-ILCompiler-Graph-Perf` to distinguish between the two.
