This offloads the processing of tx_queue to a work so the callbacks

If NET_L2_BT is enabled we need enough acl_in_pool needs to be big

When NET_L2_BT the memory pressure for fragments can be quite high
since that would be transfering IP packets which are considerable big
so this makes our frag_pool to be of the same size as NET_BUF_TX_COUNT.

When a segment could not be allocated it should be possible to resume
sending it later once previous segments complete, the only exception is
when there is no previous activity and we are unable to alocate even the
very first segment which should indicate to the caller that it would
block since that only happens on syswq the caller might need to defer to
another thread or resubmit the work.

Functions like `setup_ipv4` or `setup_ipv6` might already use the
`counter` semaphore, therefore it should be initialized before these
functions are called.
As a result of this issue, the network stack could stall until timeout
under certain circumstances (e.g. when OpenThread was used).

An expired IPv6 router would cause an infinite loop where
iface_router_run_timer() repeatedly scheduled a work item. In some
conditions it would schedule with negative delay, in other conditions
the infinite loop wouldn't happen until a router was added again.
Get rid of the router from active_router_timers when it is removed.

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.

If the whitelist already exists in the controller then the controller
should not add the device tot the whitelist and should return success.
In that case the counting of entries in the whitelist in the host will
be wrong.
Remove all whitelist counting in the host, and instead rely on the error
reported by the controller for this.
The controller should return error if the whitelist is full.
The controller should return error if use of whitelist was requested but
the whitelist was empty.
