Rename a few CAN API functions for clarity and consistency with other
Zephyr RTOS APIs.
CAN_DEFINE_MSGQ() becomes CAN_MSGQ_DEFINE() to match K_MSGQ_DEFINE().
can_attach_isr() becomes can_add_rx_filter() since a filter callback
function is not an interrupt service routine (although it is called in
isr context). The word "attach" is replaced with "add" since filters are
added, not attached. This matches the terminology used is other Zephyr
APIs better.
can_detach() becomes can_remove_rx_filter() to pair with
can_add_rx_filter().
can_attach_msgq() becomes can_add_rx_filter_msgq() and documentation is
updated to mention its relationship with can_add_rx_filter().
can_register_state_change_isr() becomes can_set_state_change_callback()
since a state change callback function is not an interrupt service
routine (although it is called in isr context). The word "register" is
replaced with "set" since only one state change callback can be in
place.

Change the can_tx_callback_t function signature to use an "int" (not an
uint32_t) for representing transmission errors.
The "error" callback function parameter is functionally equivalent to
the return value from can_send() and thus needs to use the same data
type and needs to be able to hold negative errno values.

Remove the DT_CHOSEN_ZEPHYR_CANBUS_LABEL macro and replace it with
DEVICE_DT_GET(DT_CHOSEN(zephyr_canbus)) were possible.
Where both devicetree CAN controllers and Kconfig specified CAN loopback
controllers are supported, the macro is replaced with
DT_LABEL(DT_CHOSEN(zephyr_canbus)) for now.
This is the first pass for removing the requirement for devicetree
labels for CAN controllers.

Rename the Zephyr chosen property for specifying the default CAN bus
controller from "zephyr,can-primary" to "zephyr,canbus".
The "zephyr,can-primary" property name was selected in antipation of
adding support for redundant CAN networks, which we have yet to
add. Meanwhile, the "primary" term causes confusion for non-redundant
CAN bus configurations (and the "can" term doesn't match the name of the
Zephyr CAN bus subsystem).
The CAN in Automation (CiA) 302-6, which deals with CANopen network
redundancy, uses the terms "default interface" and "redundant
interface". If/when we add support for redundant CAN networks, the
"zephyr,canbus" chosen property can be supplemented with a
"zephyr,canbus-redundant" chosen property.

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 previous API can't change the sampling-point and only allowed
bitrates that fit the time segments.
The new API allows for shifting the sampling-point and adjusts the
number of time quantum in a bit to all more possible bitrates.
The functions to calculate the timings are moved to the can_common file.
They can be used for all drivers.

Convert CAN to use a chosen node property that is similar to how we
handle zephyr,entroy or zephyr,flash-controller as the means to select a
specific peripheral instance utilized by a subsystem.
Replace references of the form:
alias {
can-primary = &can1;
};
with:
chosen {
zephyr,can-primary = &can1;
};
Replace various macro/define references with either
DT_CHOSEN(zephyr_can_primary) or replace DT_ALIAS_CAN_PRIMARY_LABEL
with DT_CHOSEN_ZEPHYR_CAN_PRIMARY_LABEL.

Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.
