Moves the Mesh AES-CCM module out into a separate module, to make it
accessible from other subsystems. Adds the new CCM API in
include/bluetooth/crypto.h along with the bt_encrypt functions.

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.

Make it possible to provision devices over advertising bearer (PB-ADV).
Many messages in the provisioning protocol are the same for provisioner
and device so much of the code could be reused by only changing when
they are expected to arrive.
This introduces to concept of local and remote device keys. The models
for cfg_cli and cfg_srv have been updated to reflect this concept. Both
the send and receive path in the transport layer have been updated to
support encrypting/decrypting with local and remote device keys.
When a node has been provisioned it is stored in bt_mesh_net.nodes. If
CONFIG_BT_SETTINGS is enabled, they are also saved to settings. If the
callback node_added in bt_mesh_prov has been set, it will be called for
every node that gets provisioned. This includes when they are retrieved
from settings.
The configuration CONFIG_BT_MESH_NODE_COUNT controls how many nodes that
can be provisioned.

Static variables and functions don't need #ifdefs if the code calling
them is using IS_ENABLED(). If IS_ENABLED() evaluates to false the
compiler will strip out all the static entities.

We've already got GATT services in subsys/bluetooth/services so
subsys/bluetooth/mesh is a more natural place. Aditionally this aims
to fix the Kconfig dependencies to be able to use mesh together with
BT_CUSTOM (i.e. a custom, potentially non-HCI, host stack).
