Henrik Brix Andersen a57db0ddcb drivers: can: rework support for manual bus-off recovery
Since all CAN controllers drivers seem to support automatic recovery (for
any future drivers for hardware without this hardware capability this can
easily be implemented in the driver), change the Zephyr CAN controller API
policy to:

- Always enable automatic bus recovery upon driver initialization,
  regardless of Kconfig options. Since CAN controllers are initialized in
  "stopped" state, no unwanted bus-off recovery will be started at this
  point.

- Invert and rename the Kconfig CONFIG_CAN_AUTO_BUS_OFF_RECOVERY, which is
  enabled by default, to CONFIG_CAN_MANUAL_RECOVERY_MODE, which is disabled
  by default. Enabling CONFIG_CAN_MANUAL_RECOVERY_MODE=y enables support
  for the can_recover() API function and a new manual recovery mode (see
  next bullet). Keeping this guarded by Kconfig allows keeping the flash
  footprint down for applications not using manual bus-off recovery.

- Introduce a new CAN controller operational mode
  CAN_MODE_MANUAL_RECOVERY. Support for this is only enabled if
  CONFIG_CAN_MANUAL_RECOVERY_MODE=y. Having this as a mode allows
  applications to inquire whether the CAN controller supports manual
  recovery mode via the can_get_capabilities() API function and either fail
  or rely on automatic recovery - and it allows CAN controller drivers not
  supporting manual recovery mode to fail early in can_set_mode() during
  application startup instead of failing when can_recover() is called at a
  later point in time.

Remove all usage of CONFIG_ZTEST_NEW_API from tests and sample as this
is now enabled by default.

Kumar Gala b582e5df99 tests: drivers: can: shell: increase test stack size
The test fails with a stack overflow on qemu_x86 when we build with
llvm.  Bump the test stack a little addresses the issue.

Henrik Brix Andersen 11ed7d62b7 tests: drivers: can: add test for the CAN shell module
Add test for the CAN shell module.

The tests execute a set of CAN shell module commands against a CAN
controller driver mock, verifies that the expected CAN controller driver
API functions are called, and that their arguments are as expected.
