Fixed #36478 -- Fixed inconsistent mail attachment handling.

Fixed an inconsistency between EmailMessage.attach() and .attachments
when attaching bytes content with a text/* mimetype. The attach()
function decodes UTF-8 bytes if possible and otherwise changes the
mimetype to application/octet-stream to preserve the content's unknown
encoding (refs #27007). Providing equivalent content directly in
EmailMessage.attachments did not apply the same logic, leading
to an "AttributeError: 'bytes' object has no attribute 'encode'"
in SafeMIMEText.set_payload().

Updated EmailMessage._create_mime_attachment() to match attach()'s
handling for text/* mimetypes with bytes content. Updated test cases
to accurately cover behavior on both paths.
