This commit enhances the CAN API test. In the send_receive tests,
we are using two filters and frames at the same time to check
if the frame gets dispatched to the correct filter.

If the prescaler is zero in the test, a div by zero would happen.
Add an assert to check for zero prescaler.

Added tests for the timing algorithm.
The tests calculate timings for some bitrates with sample-points
and verify the results.

Reordering of the struct elements to match the Linux format.
The __packed() is not necessary anymore.
std_id and ext_id is merged to id in the frame and filter.
Additionally, the frames are ready for CAN-FD.

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.

... because it is (required).
This makes a difference when building with CMake and forgetting
ZEPHYR_BASE or not registering Zephyr in the CMake package registry.
In this particular case, REQUIRED turns this harmless looking log

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.

This commit introduces the can-primary alias to identify
the primary CAN interface.
This alias is used for all samples and tests, so they don't

The seasonal overhaul of test identifiers aligning the terms being used
and creating a structure. This is hopefully the last time we do this,
plan is to document the identifiers and enforce syntax.
The end-goal is to be able to generate a testsuite description from the
existing tests and sync it frequently with the testsuite in Testrail.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

class (CAN) is enabled than enable the driver for that class
(CAN_STM32). Also have the STM32 CAN driver depend on being on a STM32
