Proper use of the CCS811 requires maintenance of the BASELINE
register value measured in clean air at various points in the sensor
life cycle. The sensor driver abstraction has no facility to support
this, so add an application header with functions to fetch and update
the register value.

Add the standard suite of trigger configuration options. Add driver
support for the DATA_READY and THRESHOLD triggers. Note cross-module

The original implementation relied on the DATA_READY bit of the STATUS
register to indicate when a reading was available. This bit remains
clear for the first several readings produced by the CCS811.
When INT_DATARDY is set in MEAS_MODE the nINT signal will remain
asserted until ALG_RESULT_DATA is read. If this is treated as a LEVEL
signal, which is the common case in Zephyr, gating the read of
ALG_RESULT_DATA on DATA_READY means the signal will never be cleared,
and the interrupt callback will be repeated immediately.
Since the STATUS register value is part of the ALG_RESULT_DATA block
just read the whole thing, and provide its content to the user only if
the DATA_READY bit is set.

The CCS811 has a measurement lifecycle that includes certain timing
constraints, including that calibration constants should not be applied
until the conditioning period has completed. If a device resets but the
CCS811 remains the process of inspecting current state and initializing
the device properly can be complicated.
Simplify this by forcing a reset of the device when the driver is
initialized. Should this cause hardship the necessary logic and
infrastructure to record time-of-last-reset across reboots and verify
measurement mode/baseline consistency can be added at that point.

The CCS811 can be in either boot mode (after powerup) or application
mode, and these modes have distinct register maps that share only some
content. The register written to switch from boot mode to application
mode is not available in application mode, so don't write to it in that
case.
Also respect the required timeout between APP_START and next I2C
operation.

Fix error in calculation of the minimum discardable buffer size. For
the LE Advertising Report the maximum payload is 31 bytes plus
additional data in the event gives an event size of 41 bytes (given that
num_reports is 1). Since this is a meta event we need to include the
sub-event code, plus the event header of 2 bytes. Total of 44 bytes.
This is a regression from afa9c42d75 where we forgot th 1 byte for the
RSSI that is appended after the data. Easy to miss since it is not part
of the struct.

RTT backend was treating synchronous mode (LOG_IMMEDIATE) and panic
mode in the same way. That lead to decreased bandwidth since after
each transfer operation backend was pending until RTT data is read by
the host. It is vital only in panic mode to ensure that device do not
reset before all data is read by the host. In synchronous mode that
degrades performance significantly.
Added distinction between those two modes.

Remove re-using connection objects in disconnected state when creating
directed advertiser or establishing a connection as a central using
direct connection procedure.
This makes the API mores consistent it terms of which connection roles
can be started from the disconnected callback.
This also avoids a central connection object being re-used for a
connection as a peripheral instead and vice versa.
When attempting to create a new connection the API would returning
a valid connection object if there is already an existing connection
object.
This existing connection object could be either in the process of
establishing the connection or already connected.
Returning the connection object in this would give the false impression
that the stack has initiated connection procedure, when in fact it just
returned an existing connection object.
The application has the ability to check for existing connection objects
using the bt_conn_lookup_addr_le API.
Add warning plus comment possible scenarios why the a valid connection
object might exists. Most important is to explain why a valid connection
object exists during the disconnected callback.
