failure during Broadcast ISO establishment, and during an
already established Broadcast ISO sync.

When an ISO stream fails to sync to a broadcaster within the first 6
events, the establishment fails (as expected). However, it did not stop
the ticker, and subsequently it was impossible to establish a new sync
after this.
Make asynchronous call to ticker_stop when establishment fails, and exit
done handling. Cleanup is handled via ll_rx_dequeue().

When the ISO sync receiver has been disabled (terminted), ULL now calls
lll_sync_iso_flush in lower link layer, to allow cleanup and releasing
of resources.
Make sure ISO sync LLL flush is also called when terminating a stream
from local side (app). Add blocking mayfly call to lll_sync_iso_flush in
ll_big_sync_terminate.

The BIG handle for an ISO sync receiver is provided by the host. The
valid range is [0x00..0xEF], and this requires the controller to allow
non-consecutive handle numbering. This means that even if only one sync
set is supported, a BIG handle of ex. value 2 must be supported.
As the code uses indexing and range checking directly by handle, this
needs to be changed. Introducing the handle index, which sequnces the
handles such that index = 0 is always the "first handle", regardless
of value.

Those replacement have been done consequently:

- `/BT_WARN/LOG_WRN/`
- `/BT_INFO/LOG_INF/`
- `/BT_HEXDUMP_DBG/LOG_HEXDUMP_DBG/`

Also, some files were relying on the `common/log.h` include to include

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.
