Intention of the test is to abort rx few bytes after start of
transmission (before it is completed). Previously, thread was busy
waiting after start of TX and aborted RX from that context. However,
it may happen that CPU is busy handling UART transfer and
k_busy_wait prolongs beyond full transfer which results in test
failure.
Move rx_abort to k_timer timeout which is run in interrupt
context.

Add a test case that ensures that uart_rx_enable() can be successfully
called after RX is disabled with uart_rx_disable() and also when it is
disabled automatically after the provided RX buffer is filled up.

Since drivers implement a callback based on action and not the state,
we should be using the API based on the action instead of the one based
on the state.

Updated uart_rx_enable() and uart_tx() to use timeout given
in microseconds. Previously argument was given in milliseconds.
However, there are cases when milliseconds granularity is not
enough and can significantly reduce a throughput, e.g. 1ms is
100 bytes at 1Mb.
Updated 4 drivers which implement asynchronous API. Updated
places where API was used.

Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

The verb tense for the suspended state was not consistent with other

The difference between low power and suspend states is a thin blur line
that is is not clear and most drivers have used indistinctly. This patch
converges to the usage of the suspend state for low power, since
contrary to the low power state, it is used by both system and runtime
device PM. The low power state is still kept, but its future is unclear
and needs some discussion.

Move all PM_DEVICE_STATE_* definitions to an enum. The
