Accept `&AssetPath` instead of `&str` in `AssetPath::resolve`

[Shatur]

What problem does this solve or what need does it fill?

AssetPath::resolve and AssetPath::resolve_embed accept &str and parse it internaly. But if you already have AssetPath, it's wasteful to call .to_string and let resolve parse it again:

bevy/crates/bevy_asset/src/path.rs

Lines 424 to 428 in 8813c18

	if let Some(label) = path.strip_prefix('#') {
	// It's a label only
	Ok(self.clone_owned().with_label(label.to_owned()))
	} else {
	let (source, rpath, rlabel) = AssetPath::parse_internal(path)?;

What solution would you like?

Accept &AssetPath instead of &str in AssetPath::resolve looks like a better API to me.

What alternative(s) have you considered?

Add _str suffix to the current methods and and new methods that accept &AcceptPath.
