Gary Pendergast 9ff54f214f General: Add a sanitize_textarea_field() function. ...

Like its predecessor (`sanitize_text_field()`), `sanitize_textarea_field()` is a helper function to sanitise user input. As the name suggests, this function is for sanitising input from `textarea` fields - it strips tags and invalid UTF-8 characters, like `sanitize_text_field()`, but retains newlines and extra inline whitespace.

Props ottok, nbachiyski, chriscct7, pento.
Fixes #32257.
