wasi_nn.h uses too generic names

[yamt]

wasi_nn.h uses too generic names like success busy.
they are prune to confilct with unrelated things.

i'd suggest to name them as wasi_ephemeral_nn_success etc.
maybe it's too late to change for the legacy wasi_nn.
but i hope we can still change them for wasi_ephemeral_nn.

Those error codes are used in a wasi-nn programming context, and programmers should be able to understand what kind of error they are dealing with. But, if it is helpful and friendly, I am open to this suggestion.

i'm not saying programmers can't understand. of course they can.

for example, if your program uses wasi-nn and another third-party library X and if the library X uses similar naming conventions, names like "success" can easily conflict.
