Adds nkJSObject.DotNetVersionFixups for dotnet 10.0

[squarebananas]

Adds a nkJSObject.DotNetVersionFixups function to apply dotnet 10.0 fixups.

Calling this function allows net10.0 to be added as a target framework for the nkast.Wasm projects and Kni.BlazorGL. It does so by adding back the removed Module, BINDING.conv_string and Blazor.platform.getArrayLength definitions, but only if they are missing. This means no changes will occur to the original implementations when using net8.0.

In the case of Kni, adding window.nkJSObject.DotNetVersionFixups(); at the beginning of the existing window.initRenderJS function in index.html will ensure the fixups are in place at startup. I have added this to nkJSObject as this serves as a base object for most things, however this could be moved to another location if preferred.

I don't see what else we can do with Module, until we remove .net8 and replace this inplace.
On the long run, I expect that this will not live in a global, and we have to pass it as an argument on every function. But right now, blazor support one WASM module per page.

The only place we use BINDING.conv_string
is in nkJSObject.ReadString(...)

Wasm/Wasm.JSInterop/wwwroot/js/JSObject.8.0.11.js

Line 70 in 716455e

var str = BINDING.conv_string(pt);

Is it possible to inline the code there, assuming it works on both .net8 and .net10 ?

For getArrayLength(...) my plan was to pass the length from the C# side, but that will require some time.

What would the reason for that be, compared to say having it accessible by window.nkJSObject.Module or something?

Yeah. I had it so that all the original net8.0 implementations would not be replaced for now though. Mainly for testing that everything works as expected when switching between net8 and net10. I can just replace that if you prefer though.

I can sort a PR for that if you want.
