_upload_and_send() uploaded raw bytes and used the 'url' key for all rooms. In E2EE rooms, media must be encrypted client-side with encrypt_attachment(), the ciphertext uploaded, and the 'file' key (with key/iv/hashes) used instead of 'url'. Now detects encrypted rooms via state_store.is_encrypted() and branches to the encrypted upload path. Refs: PR #9822 (charles-brooks)

What does this PR do?
Fixes outbound Matrix attachments in encrypted rooms.
Today the Matrix gateway always uploads the original bytes and sends a plain
urlpayload. That works for unencrypted rooms, but it is not the correctevent shape for E2EE rooms. In encrypted rooms we need to encrypt the upload
payload first, send the encrypted bytes to the homeserver, and include a
Matrix
fileobject in the event content so clients can decrypt the media.This change keeps the unencrypted path unchanged and only switches behavior
when the room is marked encrypted in the Matrix state store.
