Formatting: Prevent wp_slash from returning non-strings as strings.

Browse Source 
If a bool/float/int is passed into wp_slash it will be coerced into a string.

This changes the behavior to only slash strings. At the same time, handles recursion a little nicer by calling array_map for arrays.

Fixes #42195, #24106.
