drivers: can: drop POSIX from the native Linux SocketCAN driver name

Browse Source 
Rename the native Linux SocketCAN driver to reflect that it can can now be
used in both native_posix and native_sim (with or without an embedded
C-library).

* The native Linux SocketCAN driver, which can now be used in both :ref:`native_posix<native_posix>`
and :ref:`native_sim<native_sim>` with or without an embedded C-library, has been renamed to
reflect this:
* The devicetree compatible was renamed from ``zephyr,native-posix-linux-can`` to
:dtcompatible:`zephyr,native-linux-can`.
* The main Kconfig option was renamed from ``CONFIG_CAN_NATIVE_POSIX_LINUX`` to
:kconfig:option:`CONFIG_CAN_NATIVE_LINUX`.
