feat(wasmparser): enable component-model async ABI

[rvolosatovs]

Enable component-model async ABI by default in wasmparser

According to the doc:

/// The [Default] implementation for this structure returns the set of
/// supported WebAssembly proposals this crate implements. All features are
/// required to be in Phase 4 or above in the WebAssembly standardization
/// process.

wasm-tools/crates/wasmparser/src/features.rs

Lines 120 to 123 in b237793

	/// The [`Default`] implementation for this structure returns the set of
	/// supported WebAssembly proposals this crate implements. All features are
	/// required to be in Phase 4 or above in the WebAssembly standardization
	/// process.

I'm not quite sure where to track the progress of this proposal, but I'm guessing we're not there yet, so leaving this in draft for now.
