46a1bb7cdd usb: cdc_acm: select SERIAL_HAS_DRIVER and SERIAL_SUPPORT_INTERRUPT
USB CDC ACM is a serial driver like another. Therefore select both
SERIAL_HAS_DRIVER and SERIAL_SUPPORT_INTERRUPT. This allows one to
enable the console driver without having to enable another serial
driver.

3eda3b61f8 usb: cdc_acm: fix interrupt mode
The CDC ACM driver has to emulate the TX and RX interrupts from the USB
ones. However it does not correctly emulate them as "TX buffer empty"
and "RX buffer not empty" interrupts.

For "TX buffer empty" interrupt:
- Reading the interrupt status should not clear the interrupt
- Enabling the interrupt should fire an interrupt if the TX buffer is
  empty
- An interrupt should be triggered when the USB device get configured

For "RX buffer not empty" interrupt:
- Reading the interrupt status should not clear the interrupt
- Enabling the interrupt should fire an interrupt if the RX buffer is
  not empty

This make the a console on the USB CDC ACM port usable for the shell
and the logs.

e344e5752c ext: debug: segger: Fix SEGGER header inclusion
Fix issue caused by 3fc497ac9a

This change removes `rtt` and `systemview` from header includes
as these are already placed in the path.

Also `SEGGER_SYSVIEW_ConfDefaults.h` header included from
`SEGGER_SYSVIEW_Int.h` is placed higher to make sure `INLINE`
definition is properly visible.

7c68befb15 logging: Fix initial log level in shell
Shell log backends were initialized from shell context. After
lowering logger thread priority order has been flipped. That
revealed a bug where shell logger backend was enabled before
backend ID's has been assigned during logger initialization.

ID assignment is moved to log backend enabling function making
it independent of order of initialization.

dcc6eddfef net/ethernet: Centralize where and when header is filled in
Current code generating Ethernet header is scattered all over the place,
sometimes in functions that are supposed to check something (and not
filling the header). Not to say about innefficiency.

Src ll address does not need to be set in L2 as net_if.c handles that
already.

Broadcast dst ll address is the same in ipv4 or ipv6, thus factorizing.
In each case, multicast is filled in only at the relevant place.

This is the first step towards changing L2 sending logic, when L2 send
API function will be the only point of sending. The redirection from
driver to L2 again (which finally uses the right device API function to
send) it a temporary hack.

This simplifies the code but will also enable using statically
allocated net_buf and ethernet header payload buffer afterwards.
