Evaluate CONFIG_LINKER_ITERABLE_SUBALIGN in CMake instead of in the
linker script.
It cannot be assumed that a linker generator implementation is
pre-processed and therefore Kconfig settings cannot be used in those
but must be evaluated in CMake.

conn_mgr now fires:
- NET_EVENT_L4_IPV4_CONNECTED
- NET_EVENT_L4_IPV4_DISCONNECTED
- NET_EVENT_L4_IPV6_CONNECTED
- NET_EVENT_L4_IPV6_DISCONNECTED
These events track whether there are any ready ifaces offering
specifically IPv4 or specifically IPv6 connectivity.

Don't track up/down blame separately.
Instead, track a single last-blame iface.
Don't track blame iface inside set_ready.
Instead, track directly inside handle_update.
These two changes will simplify the addition
of blame for IPv4- and IPv6-specific events.

Instead of incrementing and decrementing global counter,
just recompute the ready-count from scratch every time
conn_mgr_mon_handle_update is called.
This will simplify the introduction of additional ready count types.
This should have no externally observable impact on the behavior of
conn_mgr.

As connectivity backends need to be bound in the same file that the
`net_if` is created in, define a common backend type for WiFi modems.
All WiFi modems should be controllable through the `wifi_mgmt` API, so
there should be no need for dedicated context.
When enabled, the particular implementation to be used is chosen through
`CONNECTIVITY_WIFI_MGMT_IMPL`. For now, the only choice is an
application defined backend.

Add a helper allowing connectivity implementations to more easily access
connectivity flags on connectivity bindings.
Signed-off-by: Georges Oates_Larsen <georges.larsen@nordicsemi.no>
Adds conn_mgr_binding_lock/conn_mgr_binding_unlock, which connectivity
implementations can call to lock or unlock the passed in connectivity
binding.
This allows connectivity implementations to safely make direct accesses
to binding data from outside conn_mgr_conn_api callbacks, and should
allow cleaner, more robust connectivity implementations to be written.

Splits many definitions from conn_mgr_connectivity.h off into their own
header, conn_mgr_connectivity_impl.h
conn_mgr_connectivity.h now focuses solely on user/application-facing
APIs, and conn_mgr_connectivity_impl now contains all functions, utils,
definitions intended for use by connectivity implementations, including
conn_mgr_if_get_binding, which is now available for use by connectivity
implementations.
This lays the foundation for allowing connectivity implementations
easier and safer access to their internal state through internal APIs.

Statically created threads with K_THREAD_DEFINE() are launched only
after the SYS_INIT phase. This does not play well with NET_CONFIG
library, which may block during SYS_INIT until network interface
is UP and RUNNING.
In order to be able to connect to L2 network and thus mark the
network interface as running and unblock NET_CONFIG, we need to be
able to run conn_mgr thread during SYS_INIT. This can be achieved,
by starting the thread dynamically during SYS_INIT phase, instead
of relying on static thread creation.

To further reduce the need for networking boilerplate in applications,
provide bulk versions of net_if_up, net_if_down, conn_mgr_if_connect,
and conn_mgr_if_disconnect that affect all available / eligible ifaces
at once.
Since it is not intuitive whether these functions should affect ifaces
which conn_mgr is ignoring, these functions take an argument that allows
this to be specified by the application.

To reduce the amount of boiler-plate needed in applications, this commit
grants conn_mgr the ability to automatically take ifaces that have given
up on connecting into the admin-down state.
Tests adjusted as appropriate.
This behavior can be disabled globally by disabling
NET_CONNECTION_MANAGER_AUTO_IF_DOWN, or disabled per-iface using the
CONN_MGR_IF_NO_AUTO_DOWN flag.

To reduce the need for boilerplate in application code, conn_mgr now
supports an auto-connect feature on all ifaces with connectivity
bindings.
conn_mgr will automatically call conn_mgr_if_connect on any iface with a
connectivity binding that enters the admin-up state, unless the newly
added CONN_MGR_IF_NO_AUTO_CONNECT flag has been set for that iface.
Also adjust automated tests to account for and take advantage of this
behavior.

Until now iterable sections APIs have been part of the toolchain
(common) headers. They are not strictly related to a toolchain, they
just rely on linker providing support for sections. Most files relied on
indirect includes to access the API, now, it is included as needed.

Rather than raise error on connect if iface is down, just take the iface
up.
Rather than raise error on disconnect if iface is down, just ignore the
disconnection request.
Adjust tests and documentation accordingly.
This should make the API easier to use for applications and is more in
line with the original L2 agnostic connectivity RFC.
Also replace some instances of net_if_flag_is_set with
net_if_is_admin_up, which is cleaner and identical in function.

The current method for handling DAD directly tracks a DAD state for each
iface.
This does not reflect the fact that each individual IP has a separate
DAD state.
This also does not align with the logic in conn_mgr_initial_state, which
instead uses net_if_ipv6_get_global_addr(NET_ADDR_PREFERRED, ...).
Thus, the current approach falsely reports IPv6 ready when DAD adds
the link_addr, and also fails to report IPv6 ready if DAD is disabled.
This commit removes DAD tracking completely, and relies solely on
net_if_ipv6_get_global_addr(NET_ADDR_PREFERRED, ...), fixing both
problems, and simplifying the event tracking.
For consistency, slight modifications to IPv4 handling as well.

Currently, conn_mgr fires L4_CONNECTED and L4_DISCONNECTED events for
every individual iface that gains or loses connectivity.
After this commit, these events are only fired when the first iface gains
connectivity, and the last iface loses connectivity, respectively.
This is so that applications can rely on conn_mgr as a simple way to
track whether connectivity is available.

Adds a flag to allow ifaces and L2s to be ignored.
This is so that applictions have better control over what ifaces they
want connectivity management for.
Enabling the flag forces conn_mgr to consider the iface
unready.
Also increase NET_CONNECTION_MANAGER_PRIORITY default value from 0 to 1
so that applications can register SYS_INIT callbacks that fire just
before conn_mgr initializes. This allows ignored ifaces to be configured
before conn_mgr starts, if needed.
