Don't pack fragments as efficiently for plaintext records

This partially reverts
https://boringssl-review.googlesource.com/c/boringssl/+/72275

The more efficiently packing broke a project that talks to a server that
does not handle this correctly. See b/378742138. For now, just match
what we do in TLS and only pack encrypted records.

Since DTLS 1.2 only has multi-message flights in the plaintext epoch and
DTLS 1.3 only has them in encrypted epochs, this effectively limits the
optimization for DTLS 1.3. Later we'll want to add a toggle and roll
this out across the board, but for now just partially revert the
behavior.
