[NativeAOT-LLVM, WASM] Import methods example missing in documentation and samples

[wadim-al]

Hi, is it possible to add Import methods example to documentation and samples?

What would you like to see? We mention [WasmImportLinkage] here: https://github.com/dotnet/runtimelab/blob/feature/NativeAOT-LLVM/docs/using-nativeaot/compiling.md#webassembly-module-imports.

For "normal" (aka statically linked) PInvoke, we also have https://github.com/dotnet/runtimelab/blob/feature/NativeAOT-LLVM/docs/using-nativeaot/wasm-interop.md.

I would like to see:

1. examples on calling JS from С# and calling C# from JS
2. explanation why [JSExport] and [JSImport] are not an option, because those work with .net 10 WASM AOT
3. more information on the mentioned emscripten ways to perform calling JS from С# and calling C# from JS if it is what should be used
4. whether I need to marshal complex stuff like arrays of structs and working approaches or links to working examples/docs
5. ideally - adding the sample which can be installed with

dotnet new install Microsoft.NET.Runtime.WebAssembly.Templates.net10
dotnet new wasmbrowser

ported to the NativeAOT-LLVM
