3c5bf5089a Bluetooth: host: add dedicated WQ for long-running tasks
Send long-running tasks to a dedicated low-priority workqueue.

This shouldn't increase memory usage since by doing this, we get rid of the
ECC processing thread.

This should fix issues like #43811, since the system workqueue runs at a
cooperative priority, and the new dedicated one runs at a pre-emptible
priority.

Fixes #43811

helper buffer has been added to ensure the complete packet before it
can be sent over RTT. Once the complete packet is collected it is sent

0843ef1cfa bluetooth: host: Fix reading current PHY when using extended advertising
The current PHY is read only when automatic PHY
update procedure is enabled, 2M PHY is supported and
extended advertising is enabled and this is done after
application is notified about connection. This leads
to invalid connection info PHY data which always returns
1M PHY because when using extended advertising the connection
can be established on different PHY and host does not read
this value from the controller in most cases. In order to
have a current PHY value updated we need to read it in
connection complete event before the user application
is notified about connection.

b3cddc6d27 Bluetooth: ISO: Central security request
If the required_sec_level is lower than the
conn->sec_level, the central will now initialize the
security procecure to ensure that the CIS is encrypted
properly.

The algorithm implemented is as follows:
1) Check security levels for each (acl, iso) pair
2) For those with insufficient security,
   call bt_conn_set_security
3) For those with sufficient security, connect the CIS
4) Once the ISO from 2) has been encrypted, connect the
   CIS for the specific ACL

The idea behind this was to implement similar support
for autonomous encryption as we have for L2CAP.
It is more complex for ISO as we are dealing with
an array of (acl, iso) pairs, meaning more can go
wrong.
