We can get rid of the view pool for SDU segments :)
We have to make the code slightly more complex :'(
The basic idea is always giving the original SDU buffer to `conn.c` for it
to pull ACL fragments from.
In order to do this, we need to add the PDU headers just-in-time.
`bt_l2cap_send_pdu()` does not add them before putting the PDU on the queue
anymore. They are added by `l2cap_data_pull()` right before the data leaves
`l2cap.c` for `conn.c`.
We also have to inform `conn.c` "out of band" of the real L2CAP PDU size so
it doesn't fragment across segment boundaries. This oob is the new `length`
parameter to the `.pull()` method.
This is the added complexity mentioned above.
Since SDU segmentation concerns only LE-L2CAP, ISO and Classic L2CAP don't
need this extra logic.

The current TX pattern in the host is to try to push a buffer through all
the layers up until it is ingested by the controller.
Since sending can fail at any layer, we need error-handling and separate
retry logic on pretty much all layers. That logic obscures the "happy path"
for people trying ot understand the code.
This commit inverts the control, in a way that doesn't require changing the
host or HCI driver API (yet):
Layers don't send buffers synchronously, they instead put their buffer in a
private queue of their own and raise a TX flag on the lower layer. Think of
it as a `READY` interrupt line that has to be serviced by the lower layer.
Sending is now non-blocking, rate depends on the size of buffer pools.
There is a single TX processing function. This can be thought as the
Interrupt Service Routine that will handle the `READY` interrupt from the
layers above.
That `tx_processor()` will then attempt to allocate enough resources in
order to send the buffer through to the controller. This allocation logic
does not block.
After acquiring all the resources, the TX processor will attempt to pull
data from the upper layer. The upper layer has to figure out which buffer
to pass to the controller. This is a good spot to put scheduling or QoS
logic in the upper layer.
Notes:
- user-facing API for tuning QoS will be implemented in a future patch
- this scheme could (and probably will) be extended to upper layers (e.g.
ATT, L2CAP CoC segmentation).
- this patch removes the `pending_no_cb()` memory optimization for
clarity/correctness. It might get re-implemented after a stabilization
period. Hopefully with more documentation.

Instead of allocating segments/fragments and copying data into them, we
allocate segments as "views" (or slices) into the original buffer.
The view also gives access to the headroom of the original buffer, allowing
lower layers to push their headers.
We choose not to allow multiple views into the same buffer as the headroom
of a view would overlap with the data of the previous view.
We mark a buffer as locked (or "in-view") by temporarily setting its
headroom to zero. This effectively stops create_view because the requested
headroom is not available.
Each layer that does some kind of fragmentation and wants to use views for
that needs to maintain a buffer pool (bufsize 0, count = max views) and a
metadata array (size = max views) for the view mechanism to work.
Maximum number of views: number of parallel buffers from the upper layer,
e.g. number of L2CAP channels for L2CAP segmentation or number of ACL
connections for HCI fragmentation.
Reason for the change:
1. prevent deadlocks or (ATT/SMP) requests timing out
2. save time (zero-copy)
3. save memory (gets rid of frag pools)
L2CAP CoC: would either allocate from the `alloc_seg` application callback,
or worse _steal_ from the same pool, or allocate from the global ACL pool.
Conn/HCI: would either allocate from `frag_pool` or the global ACL pool.

This option allows you to look up a struct device from any of the
node labels that were attached to the devicetree node used to create
the device, etc.
This is helpful because node labels are a much more human-friendly set
of unique identifiers than the node names we are currently relying on
for use with device_get_binding(). Adding this infrastructure in the
device core allows anyone to make use of it without having to
replicate node label storage and search functions in various places in
the tree. The main use case, however, is for looking up devices by
node label in the shell.
Since there is a footprint penalty associated with storing the node
label metadata, leave this option disabled by default.

Add the following new macros:
- DT_FOREACH_NODELABEL
- DT_FOREACH_NODELABEL_VARGS
- DT_INST_FOREACH_NODELABEL
- DT_INST_FOREACH_NODELABEL_VARGS
These are for-each helpers for iterating over the node labels of a
devicetree node. Since node labels are unique in the entire
devicetree, their token representations can be useful as unique IDs in
code as well.
As a first user of these, add:
- DT_NODELABEL_STRING_ARRAY
- DT_INST_NODELABEL_STRING_ARRAY
The motivating use case for these macros is to allow looking up a
struct device by devicetree node label in Zephyr shell utilities.
The work on the shells themselves is deferred to other patches.
To make working with the string array helpers easier, add:
- DT_NUM_NODELABELS
- DT_INST_NUM_NODELABELS

The original intention was that the audio buffers supplied by
application to the UAC2 API can be directly used by UDC driver.
The buffer alignment requirement was explicitly stated with regards
to the receive buffer, but was mistakenly omitted on transmit buffer.
While the missing comment is added, mention also that the buffer has to
be otherwise suitable for use by UDC driver, because alignment might not
be the only UDC driver requirement. For example, the UDC driver can
require the buffer to reside in memory region that it can access with
DMA.
