Implement a CAN shell. With this shell you can send messages,
attach and tetach filters.
Messages that match the attached filters are printed to the shell.

The filenames of the can drivers were not consisten.
Changed them to can_<dev name>

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

can_attach_msgq can be implemented as a wrapper of can_attach_isr.
This is implemented as a common function for all drives and reduces
the complexity of the specific drivers. Since this is common to
multi instances of drivers too, it is removed from the API struct.

The MCP2515 is a CAN controller that can be connected via SPI to an
host MCU. This driver adds support for the MCP2515 as a new driver in
the CAN subsystem.
As it is a SPI peripheral it uses a thread for its interrupt
handling and the received message filtering is done inside this
interrupt thread, as the MCP2515 filter capabilities are not sufficient
for the Zephyr CAN interface.
The driver was validated with an external CAN logger and the adjusted
CAN sample application.

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.
