The `xxx_ipv6multicast` function in each driver is not adapted to
multiple IPv6 addresses yet, and they're redundant, so try to take them
into common code.
Change:
1. Add MAC `g_ipv6_ethallnodes` and `g_ipv6_ethallrouters` in
`icmpv6_devinit` and call them in `netdev_register`
2. Add multicast MAC for Neighbor Solicitation when adding any IPv6
address, and remove them when IPv6 address is removed
3. Select `NET_MCASTGROUP` when `NET_ICMPv6` because now we need
`d_addmac` when we have ICMPv6
Note:
We want modules outside net stack to call functions like
`netdev_ipv6_add` and never touch the related MAC address, so these MAC
functions are added as internal functions to `net/netdev/netdev.h`

1. Supporting `SIOCSIFADDR` and `SIOCDIFADDR` with Linux in6_ifreq struct to manage ipv6 addresses.
Ref: https://man7.org/linux/man-pages/man7/netdevice.7.html
2. Supporting alias like 'eth0:0' for multiple IPv6 addresses, to keep previous ioctl `SIOCGLIFADDR`, `SIOCSLIFADDR`, `SIOCGLIFNETMASK` and `SIOCSLIFNETMASK` working.

Prepare for multiple IPv6 addresses per net device, then we can notify
add/remove of a single address later.

Updated alt1250 driver with regarding to the following changes.
- Add LTE hibernation feature
- Split source code per module
- Some refactoring
- Some bug fixes
We have projects that need to sense ip address changes in time,
and set ip address or clear ip address through netlink
so the relevant implementation is added.
The usage and command structure are consistent with linux

* net/netdev/netdev_ioctl.c:
(netdev_ifr_ioctl): The ioctl SIOCGIFHWADDR provides the hardware
address (e.g., Ethernet MAC, etc.) of a network interface. It is
based on Linux. (BSD-based systems don't have this ioctl.) The Linux
implementation sets sa_family to ARPHRD_ETHER for Ethernet and IEEE
802.11 interfaces [1]. NuttX was setting it to NET_SOCK_FAMILY for
these interface types as well as 6LoWPAN and PKTRADIO; this was
incorrect and also the value of NET_SOCK_FAMILY varies based on
Kconfig settings. Correcting this to ARPHRD_ETHER for Ethernet and
IEEE 802.11 and ARPHRD_IEEE802154 for 6LoWPAN and PKTRADIO.

* net/netdev/netdev_ioctl.c:
(netdev_ifr_ioctl): The ioctl SIOCSIFHWADDR sets the hardware address
(e.g., Ethernet MAC, etc.) of a network interface. Radio devices may
have different lengths of hardware addresses, such as
NET_6LOWPAN_EADDRSIZE (8), NET_6LOWPAN_SADDRSIZE (2), or
RADIO_MAX_ADDRLEN (8). Also, Kconfig CONFIG_PKTRADIO_ADDRLEN allows
the user to set any arbitrary size. Note that while the sister ioctl
SIOCGIFHWADDR "get hardware address" copies
`dev->d_mac.radio.nv_addrlen` bytes, SIOCSIFHWADDR was copying
NET_6LOWPAN_ADDRSIZE bytes unconditionally. Depending on which radio
is used, this could be incorrect. Fixing it to use
`dev->d_mac.radio.nv_addrlen` for SIOCSIFHWADDR as well. Also adding
DEBUGASSERT to ensure this is within bounds of source and
destination of the copy.
This fixes a regression caused by the following commit,
which prevents the file flag from being updated.
