Update TagListGenerator to always useReadOnlySpan<byte> properties (#8486)
## Summary of changes Update the tag list generator to always use `ReadOnlySpan<byte>` properties instead of `byte[]` ## Reason for change After moving our vendored `Span<T>` implementation into the `System` namespace, various optimizations open up to us, including using `ReadOnlySpan<byte>` properties on .NET Framework instead of `static readonly byte[]` to avoid startup costs. ## Implementation details Replace the code generated by the generator, and update the generated code ## Test coverage Covered by snapshot tests and behaviour is covered by existing tests. We'll check the benchmarks to make sure that we _don't_ see any perf impact (there shouldn't be, impact should just be reduced startup costs) ## Other details Depends on a stack updating our vendored system code - #8391 - #8454 - #8455 - #8459 - #8461 - #8469 - #8476 - #8477
