No HotReload for Azure Functions VS Code Tooling

> For issues with the Functions Visual Studio tooling, provide detailed steps to reproduce, including details about your environment (OS, VS version, etc)

Azure Functions Tooling using the C# .NET 6 isolated process function does not support the hot reload capability by default. I tried using the hot reload capability by adding a custom build target recommended here:

https://github.com/Azure/azure-functions-core-tools/issues/1239#issuecomment-669018902

But the reload on average 5 seconds, which is a poor inner loop experience.

Start by reviewing the .NET 6 isolated-process context and the custom build target recommendation linked from Azure Functions Core Tools issue #1239. Trace how the VS Code tooling currently handles hot reload and compare its behavior with the reported five-second reload time. Done means default hot reload support is implemented or the remaining limitation is clearly documented.
