Ability to set message flags for any message to send (not only for interaction messages)

[marcbal]

What feature are you proposing?

It would be nice to be able to set the SUPPRESS_NOTIFICATIONS flag to a message sent in a channel. The Javacord API only allows it in the InteractionMessageBuilder (using setFlags method), not in the MessageBuilder.

Do you have any additional material for your feature proposal?

Flags can be set for any message sent to the API (only SUPPRESS_EMBEDS and SUPPRESS_NOTIFICATIONS can be set)

Regular message can also be silenced (not only the interaction messages): https://stackoverflow.com/a/76527191
