Add a benchmark for SKData

[mattleibow]

Description of Change

This PR just updates the benchmarks project and build tooling so that it is easier to run benchmarks.

Benchmarks can be run from the IDE or via the CLI:

cd benchmarks/SkiaSharp.Benchmarks
dotnet run -c Release -f net6.0

I ran on CI: https://github.com/mattleibow/SkiaSharpBenchmarks/runs/7082633214
Download ETL + Artifacts (226MB): https://github.com/mattleibow/SkiaSharpBenchmarks/suites/7116242957/artifacts/282140555
libSkiaSharp.dll Symbols: libSkiaSharp.pdb.zip

The tests are simple and compare all the complexity of managed types and the handle registration with the raw p/invokes and I find the p/invokes are slower... somehow slower than all the managed stuff that also calls the very same p/invokes since the managed stuff wraps the p/invokes...
