Trond Einar Snekvik fc56b37116 Bluetooth: Mesh: Refactor CCM
Unifies the Mesh CCM implementation parts for encryption and decryption
into a crypt and an auth step, reducing stack usage and code size.

This change also brings several performance improvements, most notably
reducing copying of the nonce and unrolling the 16 byte XOR operations.

Performance for the Mesh worst case of a 382 byte payload with 16 bytes
of additional data (full transport encrypt with virtual address) goes
from an average of 889us to 780us on nRF52840 with default optimization
flags.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.
