Auto merge of #77997 - fusion-engineering-forks:to-string-no-shrink, r=joshtriplett
Remove shrink_to_fit from default ToString::to_string implementation. As suggested by `@scottmcm` on Zulip. shrink_to_fit() seems like the wrong thing to do here in most use cases of to_string(). Would be intereseting to see if it makes any difference in a timer run. r? `@joshtriplett`
