feat: Metrics.Set now accepts string as value

[bitsandfoxes]

From the updated dev docs: https://develop.sentry.dev/sdk/metrics/#sets Set should accept strings as value.
With this PR we're vendoring in part of force's Crc32.NET implementation because there is not anything built-in that I could find.

@bitsandfoxes did you see System.IO.Hashing.Crc32?

I guess that comes with a dependency on the System.IO.Hashing NuGet package...

Yes. Not wanting to take on the dependency is the reason why we're vendoring it in.
