This feature allows the RCP to support multiple host stacks on different PANs
by making use of the spinel Interface ID.
Created unit tests for testing multipan feature with multiple ot-instance
support.
Based on Si-Labs PR #8914 by @parag-silabs, but a little different approach.
Instead of handling everything by a single sub-mac instance, multiple
OpenThread instances are created on RCP side that map to different IID.
Thanks to this there are separate data kept for each interface. Platform
is able to determine interface by ot instance pointer passed as an argument
to most of the API functions.
Tx/scan queue was removed as it is possible to request transmission in
parallel, it is up to the platform to decide if it should fail or queue
second tx or it has two radios available.
NOTE:
Platform needs to provide different otRadioFrame of each instance and
the processing needs to take into account the instance being used.

Add a new `OT_RADIO_CAPS_RX_ON_WHEN_IDLE` radio capability which lets
OpenThread know what the radio idle state operation will be: receive
or sleep.
This allows to save power on sleepy devices since the active --> idle
transition is much faster, specially for the cases in which there is
some kind of serialization between OpenThread core and the radio
driver.
This commit makes the core pass the sensitive keys to the platform
settings initialization, so that the platform settings implementation
can know which keys are sensitive keys during the initializing and do
the migration when needed.
This commit removes application library CLI/NCP dependency on platform
layer UART APIs. Instead, application layer provides callbacks sending
CLI/NCP data.
With this change, platforms with native support for formatted output
can simply implement the CLI output callback with something like
`vprintf()`.
