Rollup merge of #78499 - SkiFire13:fix-string-retain, r=m-ou-se

Prevent String::retain from creating non-utf8 strings when abusing panic

Fixes #78498

The idea is the same as `Vec::drain`, set the len to 0 so that nobody can observe the broken invariant if it escapes the function (in this case if `f` panics)
