The common API functions in VCS had dead code in specific
configurations, causing coverity issues. Fixed by this
commit.

Change the return value from -ENOTCONN to -EINVAL as that

Instead of return -ENOTCONN they will now return -EINVAL as
that is a more appropriate return value for checking if
the pointer is NULL.

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.

The error check was removed earlier as it was assumed that
we would either get an error, or the data would be valid.
However, without an error check, we are not guarded
against bad reads.

If the output description of the server is empty (legal by the
spec), then we should not return an error to the application
when read. Also added some debug statements when the value is
truncated.

Fixes 2 issues:
1) The write callback always returned an error
2) The auto-read of the offset state did not, unlike what the
comment suggested, retry only once and fail on the second attempt,
but rather keep retrying.

Moves the callback structure for VOCS to the register function
which is renamed from init, as there's no reason to register

Fix bluetooth audio compilation issue when BT_AUDIO is enabled but
no Bluetooth host services has been enabled.
This leads to an empty library file.
Instead of creating a new library for audio add the sources to the
parent library, similar to how bluetooth services are added.
