NativeAot: Enable GC event tracing on standalone GC

[AustinWise]

Before this change, no GC events would be recorded when using dotnet trace on a NativeAOT program that uses standalone GC.

I copied the implementation from CoreCLR. The one change I made was to use a Crst instead of a spin lock.

I experimented with the changes on Windows, here are the experiments:

Experiment 1: Capturing traces using dotnet-trace without clrgc. Experiment 2: Capturing traces using dotnet-trace with clrgc. Experiment 3: Capturing traces using ETW with clrgc.

All of these worked, in the sense that PerfView can show GCStats correctly on the captured trace.
