.NET on WebAssembly - Bindings to Sentry's JavaScript SDK

[bruno-garcia]

The Sentry package as well as the new Sentry.AspNetCore.Blazor.WebAssembly work on the browser through wasm.

Related work:

• [Hackweek] Blazor Wasm SDK #2569
• Make sure Sentry.AspNetCore works with Blazor #317
• feat: Added .NET8 as TFM for Blazor.WebAssembly package #3501

We have a sample in the repo:

• Sample Blazor Wasm #574

But none of the work done yet (other than the draft PR from hackweek have done anything related to bundling our JS SDK.
This should allow us to get Session Replay, our User Feedback Widget as well as some JS specific features like Unhandled Promise Rejections, etc.
