Polly V8 Release Checklist

[martintmk]

Before officially releasing Polly V8 we should close the following issues:

• v8 API documentation #1091
• Finalize the V8 API #1301
• Add more convenience extension from v7 #1130
• Investigate native AOT compatibility #1110
• Investigate the binary compatibility of readonly structs  #1280
• Polly V8: Public API Review #1233
• Introduce samples folder #1291
• Close all outstanding issues that are addressed in V8 #1303
• Adopt Polly V8 in Microsoft.Extensions.Resilience and Microsoft.Extensions.Http.Resilience #1304
• Add Microsoft.CodeAnalysis.PublicApiAnalyzers #1090
• Reduce allocations in telemetry #1312
• Hide Simmy API for initial v8 release #1601

For 8.1 release:

• Use the new TimeProvider API from .NET 8 #1070
• Validate v8 build with .NET 8 #1141

For consideration:

• Upgrade the Polly.Samples repo to V8 #1300
• Reimplement the v7 policies on top of v8 APIs #1132 - this brings non-trivial performance hit. We should determine whether to wait and do it later as a part of code-cleanup once more people switch to V8.
• Investigate the passive timeout strategy for v8 #1133 - is this something we even want in V8 (passive timeout can lead to non-cancellable background tasks that can overwhelm the system)

@martincostello , @joelhulen Have I missed anything? Any additional tasks to add?
