`gatt_req_alloc` will wait until a `req` is free (or until timeout).
`req`s are freed on the BT RX thread in calls into bt_att_recv.
When `gatt_req_alloc` called on the BT RX thread itself when there are
no free `req`s, it will block the BT RX thread and deadlock. The
deadlock lasts until timeout.
This change detects this condition and returns the failure early.
Fixes https://github.com/zephyrproject-rtos/zephyr/issues/39624 where
if `bt_gatt_write` is called from BT RX thread (as can happen if it is
called from a bluetooth callback), the BT RX thread can be blocked and
prevented from processing the request responses and unblocking itself.
This was the cause of a soft 30s deadlock until gatt_req_alloc timeouts.

When hashing attributes for the UUID cases:
BT_UUID_GATT_PRIMARY_VAL
BT_UUID_GATT_SECONDARY_VAL
BT_UUID_GATT_INCLUDE_VAL
BT_UUID_GATT_CHRC_VAL
BT_UUID_GATT_CEP_VAL
where (handle || UUID || value) is to be hashed, the worst case size of
attribute value can be deduced from the associated union that describes
all the attribute values in the given cases.
Update the data array to accommodate for the worst case size.

There were no handling of HCI_LE_CTE_Request_Failed event.
The commit adds missing implementation. An application will
be notified about failed request by cte_report_cb. It is the
same callback that is used for reporting collected CTE IQ
samples. The same callback was used to avoid creation new callback.
To give an application possibility to distinguish between regular
IQ samples report and request failed additional member err was added
to bf_df_conn_iq_samples_report structure.

The host reassembles fragmented advertising reports from the controller.
Non-complete advertising reports from different advertisers may not be
interleaved. If non-complete advertising reports from an advertiser
is received while advertising reports from another advertiser is
reassembled, an error message is logged and the advertising report is
discarded. Future scan results may be incomplete.
Advertising reports from legacy PDUs or complete extended advertising
reports may be interleaved as these do not require reassembly.
If the controller sends more advertising data than fits in the
reassembly buffer, the data is truncated. Further advertising reports
from the advertiser are discarded until the final complete advertising
report is received and discarded.

The CTE type is used in two ways by HCI layer:
1) single value representing particular CTE type: AoA, AoD 1 us,
AoD 2 us
2) bit-filed where bits 0-2 represent particular CTE types AoA
AoD 1 us, AoD 2 us
The bit-field is used to inform Controller about allowed types
of CTE, hence single value carries more than one value.
To avoid confusion between these use cases in code that refers
to case 1) all named cte_type (singular form). For case 2)
cte_types (plural form) is used.
There is an enumeration that is used for both cases:
bt_df_cte_type. For cte_type only single value from the
enumeration may be assigned to variable except
BT_DF_CTE_TYPE_NONE and BT_DF_CTE_TYPE_ALL.
For cte_types all enum members may be used. Ocasionally
BT_DF_CTE_TYPE_NONE may be excluded. If that is true,
it is described in code documentation.
Thanks to that applications are released from requirement
to include hci.h header file.

The current implemenation of GATT long write
(ATT prepare + exec write) worked by sending
each segment individually to the application.
This was a simple and effective method, but
the application had no indication of when the
last segment had been written.
This commit reassembles all the prepare writes
for a specific handle, and then sends the combined
write data to the application.
The prepare+exec write may include multiple handles,
so the implementation has taken that into account,
and will loop over the prep_queue multiple times.
