[natives] expose all feature flags inside NativeContext as an extension

[alinush]

Description

Exposes the feature flags inside the Rust implementation of Move native functions. This is useful for the generic elliptic-curves Move module (#6550), which will be upgradeable by feature gating newly-added curves directly inside the Rust natives.

Hmm... I feel like this may not be the best way to expose feature flags to native functions.

Extensions are rather heavy-weight and involve dynamic casting. Instead, you can pass the features to the make_all function in each crate, which will then pass them down to each native function. I'd also recommend you add a features: Features field to the SafeNativeContext and make it available to natives. Notice that SafeNativeContext already contains the timed features, so we just need to replicate that pattern for features.

I'm aware that struct Features contains a vector, so we may not want to clone it often. Feel free to put it in an Arc before passing it down to the natives. Alternatively you could also change its representation from Vec to something like SmallVec, but I don't know if that's gonna work with serde.

Makes sense to me! I'll use an std::sync::Arc then & see how things work out.
