In case Controller reports to Host insufficient resources to store IQ
samples, according to BT 5.3 Core spec. Vol 4, Part E, sections
7.7.65.21 and 7.7.65.22:
1) packet_status shall be set to BT_HCI_LE_CTE_INSUFFICIENT_RESOURCES
2) sample_count shall be set to zero.
That means there should be no IQ samples stored in IQ report.
HCI implementation stored single IQ sample with value BT_HCI_LE_CTE-
_REPORT_NO_VALID_SAMPLE.
The commit fixes that. No additional memory is added to event buffer
and no IQ sample is stored if sample_count is zero.
Also there is added code that handles situation where ULL provides
IQ report with packet_status indicating valid IQ samples report
but sample_count is zero. In such case Host event stores single IQ
sample with value BT_HCI_LE_CTE_REPORT_NO_VALID_SAMPLE.
In case of vendor specific counter part of the event the value is
BT_HCI_VS_LE_CTE_REPORT_NO_VALID_SAMPLE.

Add vendor specific IQ samples report that holds IQ data in 16 bits
signed integer format. Thanks to that we preserve complete accuracy of
IQ samples provided by Nordic Direction Finding Extension in Radio
peripheral. That helps to maintain better accuracy of evaluated
angles with use of reported IQ samples.

Nordic Radio Direction Finding Extension provides 12 bits wide IQ
samples. The Bluetooth Core Specification 5.3 Vol 4, Part E sections
7.7.65.21 and 7.7.65.22 limits IQ samples to be 8 bits wide.
There are other way to convert 12 bits IQ samples into Bluetooth Core
specification compliant 8 bits IQ samples than ordinary 4 bits right
shift. If one is sure that samples will never go over 10 bits or 8
bits then, it is allowed to use 2 bits right shift or even 8 least
significant bits of 12 bits IQ samples.
The commit introduces a possibility to choose which approach is used
for IQ samples conversion in HCI layer while Host IQ report events
are created.

HCI_LE_CTE_Request_Failed may be generated in case received LL_CTE_RSP
PDU didn't contain CTE or if peer rejected the request. HCI function
encode_data_ctrl responsible for dispatching received control PDUs
should not expect a PDU with PDU_DATA_LLCTRL_TYPE_CTE_REQ opcode.
It should never happen. The correct opcode here is PDU_DATA_LLCTRL_TYPE-
_CTE_RSP.
Result of this issue is an assert when LL_CTE_RSP PDU is received
but it does not include CTE.

HCI_LE_Connectionless_IQ_Report and HCI_LE_Connection_IQ_Report
events has fields that store event counter values: Periodic_Event_-
Counter and Event_Counter, respectively.
Values assigned to this HCI events are taken directly from
lower link layer objects. In case of too slow processing of
HCI events values provided by LLL contexts could be changed before
HCI sends events to Host. That can happen e.g. in case of short
periodic advertising interval and slow UART baudrate.
In such situation event counter values will be corrupted.
To prevent that situation, event counter values connected with
IQ sample reports, has to be stored in node_rx_iq_report when
a report instance is filled in LLL.

Nordic Semiconductor Radio peripheral provides IQ samples as
12 bits signed integer with sign extended to 16 bits.
Where out of range IQ samples (saturated) have value -32768.
Due to conversion of IQ samples to 8 bit signed integer, required by
BT 5.3 Core Vol 4, Part E sections 7.7.65.21 and 7.7.65.22 the
saturation information was lost.
The PR fixes that issue by use of value -128 to mark saturated
IQ samples. Note that BT 5.3 Core does not give any particular
value of IQ sample a special meaning.
This is a vendor specific solution and does not affect other
implementations of lower link layer.
