BUILD: quic: allow USE_QUIC to work with AWSLC

This patch fixes the build with AWSLC and USE_QUIC=1, this is only meant
to be able to build for now and it's not feature complete.

The set_encryption_secrets callback has been split in set_read_secret
and set_write_secret.

Missing features:

- 0RTT was disabled.
- TLS1_3_CK_CHACHA20_POLY1305_SHA256, TLS1_3_CK_AES_128_CCM_SHA256 were disabled
- clienthello callback is missing, certificate selection could be
  limited (RSA + ECDSA at the same time)
