Mail: allow custom attachment filenames in wp_mail().

Browse Source 
Previous to this change, attachment filenames in outgoing emails could only ever be derived from their paths (passed in as a numerically indexed array of `$attachments`).

This changeset adds support for passing an associative `$attachments` array, where the key strings will be used as filenames instead.

Includes 2 new unit tests to ensure both array formats continue to work as intended.

Fixes #28407.
