[Feature Suggestion] Option to encrypt either email body, attachment or both for FlowCrypt secure compose

[martgil]

Description:
We received a user concern regarding an option for choosing whether to encrypt the email body, attachment, or both. This feature was suggested by users who encountered situations where public key encrypted files were not automatically decrypted upon download for another PGP email client they were using, which doesn't automatically decrypt upon download. Although they are aware they need to decrypt the attachment they received, they find it ineffective. Consequently, they were seeking an option to attach unencrypted attachments.
