Increase the default TX thread stack size for the CAN loopback driver from
256 to 512 bytes as the former has shown to be too little when using the
loopback driver on real hardware.

Remove the CAN_HAS_CANFD Kconfig helper symbol in order to allow enabling
CAN-FD support in the API regardless of driver support.
Change default to CAN-FD support being disabled and have samples and tests
that require CAN-FD support turn it on. This aligns the default
configuration across CAN controller drivers regardless of their
capabilities.
The rationale behind this is that we are starting to see MCUs with multiple
CAN controllers, some CAN-FD compatible, some not (e.g. NXP i.MX RT1060 and
FPGAs). Automatically enabling CAN-FD support based on the presence of a
CAN-FD capable CAN controller leads to different application default
settings based on the CAN controller(s) in use.

Update CAN drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose
the driver and enable it by default based on devicetree.

Convert the CAN loopback driver from being configured via Kconfig to
multi-instance configured via devicetree.

The loopback driver is a simple driver that can be used to
test CAN subsystems. The actual implementation sends frames
in the same thread that calls the send function.
Some libraries have problems with that behavior.
This PR implements a dedicated thread that calls the callback
for the receiving functions and a msgq in between the sender
and the TX thread.

Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

This commit implements a CAN loopback device. This device is used
for testing when no CAN controller is available on the hardware.
