[NativeAOT-LLVM] Non hybrid globalization requires JS

[yowl]

With dotnet/runtime#99956, globalization requires some JS which we wont have for WASI and don't include in the build #2543 (comment). We should do something else, use the full ICU as before, in the future maybe WebAssembly/WASI#590

@ilonatommy How is globalization working on WASI on Mono?

[ilonatommy]

WASI does not expose Intl API in the same way as browser does, so it's not possible to implement HG there. There are ongoing discussions under WebAssembly/WASI#239 or WebAssembly/WASI#25 mentioning the need to enable it.

The issue explicitly mentions non HG. Do we require JS in non HG or is this issue missleading?

[ilonatommy]

Sorry, misread it. Issue is formed correctly. For NativeName to return correct value we need JS (so HG switched on). Otherwise, we use ICU data that is shipped in reduced size form- without full NativeName info. Theoretically we could start adding that info and pump-up ICU package but already long time ago it was decided against it. I am not sure what is the size change and if custom ICU build would help here, I will need to check it. Beyond that I don't see any "easy" existing solution.

IIUC on WASI we don't correctly compute NativeName, is that right?

We return e.g. en-US when the expectation is English (United States). See the original issues about it: dotnet/runtime#44739.
