Add handling of Direction Finding node_rx_iq_report type in ULL.
This is required to correctly deliver IQ samples collected by
LLL during receive of PDU including CTE.

CTE sampling enable or disable requests should be provided to LLL.
Double buffer of lll_df_sync_cfg is added to lll_sync for that purpose
Thanks to that:
- there is no need to synchronize LLL with LL thread
- LLL has always access to valid configuration (new or former)
The configuration is stored in double buffer as instances
of lll_df_sync_cfg, not as pointers. This is the only
difference between double buffer pattern used to store adverising PDU.

IQ samples report requires information about antenna switch pattern
that was used to measure RSSI. RSSI is measured during PDU receive.
For Nordic Radio peripheral the PDU antenna is selected by first antenna
switch pattern set in SWITCHPATTERN register. That pattern is providded
by device tree. This information is already available in radio_df.c.
The information is required by LLL, that has access to functions
provided in radio_df.c. New function was provided to return PDU antenna
switch pattern.

Refactor and simplify the bluetooth buffer configurations to improve the
easy of configurations and eliminate invalid ones.
By moving configurations out of host and controller specific
configurations and into a common one it becomes easier to configure
the host and controller separately as the same configurations can be
used as would be for a combined build.
All HCI configurations are now given exluding the matching HCI header,
which eases the configuration as the application don't have to know the
different header sizes.
The BT_RX_BUF_LEN is split into ACL and Event, as well as the suprising
use of Command size.
BT_L2CAP_RX_MTU is removed as the stack does not support reassembling of
HCI ACL data to larger L2CAP PDUs. The application will have to set
ACL RX size and account for the L2CAP PDU header itself.
BT_EATT_RX_MTU was removed as it is only used for setting a different
default value for another option which leads to the stuck kconfig symbol
problem.
The configurations can be updated according to the table below:
** New configuration | ** Old configuration
All configurations
BT_BUF_ACL_RX_SIZE | BT_L2CAP_RX_MTU + 4
BT_BUF_ACL_RX_SIZE | BT_RX_BUF_LEN - 4
BT_BUF_EVT_RX_SIZE | BT_RX_BUF_LEN - 2
BT_BUF_CMD_TX_SIZE | BT_RX_BUF_LEN - 3
BT_BUF_CMD_TX_COUNT | BT_HCI_CMD_COUNT
BT_BUF_EVT_RX_COUNT | BT_RX_BUF_COUNT
BT_BUF_ACL_RX_COUNT | BT_RX_BUF_COUNT
BT_BUF_ACL_RX_COUNT | BT_ACL_RX_COUNT
BT_BUF_EVT_DISCARDABLE_SIZE | BT_DISCARDABLE_BUF_SIZE - 2
BT_BUF_EVT_DISCARDABLE_COUNT | BT_DISCARDABLE_BUF_COUNT
Controller-build
BT_BUF_ACL_TX_SIZE | BT_CTLR_TX_BUFFERS_SIZE
BT_BUF_ACL_TX_COUNT | BT_CTLR_TX_BUFFER
HCI-bridge
BT_BUF_ACL_TX_SIZE | BT_HCI_ACL_DATA_SIZE
BT_BUF_ACL_TX_COUNT | 6
Fixed invalid configurations setting either BT_L2CAP_RX_MTU or
BT_CTLR_DATA_LENGTH_MAX larger than BT_RX_BUF_LEN could lead to buffer
overruns.
Fix advertising report max data length calculation.
This always used the BT_DISCARDABLE_BUF_SIZE macro but this feature
can be turned off and advertising reports will be allocated from the RX
buffer in that case. Also controller-build does not have this buffer
(in hci_raw.c). Also the wrong HCI header was used in the calculation,
HCI event header should have been used instead of HCI ACL header.
