get_short_name should return a Cow most likely

[nicopap]

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

bevy_utils::get_short_name returns a String. This results in unconditional allocation, even if the short name can be expressed as a slice of the full name.

What solution would you like?

Returning a Cow (similarly to how from_utf8_lossy works) would reduce allocation.

What alternative(s) have you considered?

Sometimes, get_short_name is used for debug/display purposes. We could also provide a wrapper type that specifically implements Display for &str with the get_short_name heuristic to remove all type prefixes.

Additional context

I saw a "hand made" version of get_short_name in a fmt::Debug impl in asset_v2

get_short_name was moved to https://github.com/bevyengine/disqualified. Is this still relevant?
