Auto merge of #14468 - lowr:patch/expand-macro-bang, r=Veykril

Expand Macro Recursively: don't append "!" to non-bang macro name

When we run `Expand Macro Recursively`, we prepend a comment "Recursive expansion of foo! macro" to the expansion result. I've noticed we unconditionally render the macro name with "!" and, while super subtle, I feel a bit awkward when the macro is either a derive or attribute macro.
