DAP write transaction occupies 5 bytes of a command packet.
DAP read transaction needs just one byte in a command packet
and expect 4 bytes in a response.
The fixed maximal number of transactions in a packet caused
packet filling less than optimal.
Compute both command and expected response sizes based on
read or write direction of each transaction.
Run the queue if one of sizes does not fit into a packet.
The change increases the speed of the mostly read transfer
from 36 KiB/s to almost 40 KiB/s @ USB FS, adapter speed 1000
due to reduction of adapter inserted RDBUFF reads.

USB bulk backend needs to avoid zero sized USB packets
sent after each full sized packed for performance reasons.
HID backend uses fixed size HID reports so the full size
of the report can be utilized.
Introduce packet_usable_size to reflect it.

We are moving the binary helpers in files .inc in contrib/loaders/
but we have no support to disassemble them for checking their
content, nor documentation to give any hint.
Add a simple script that uses objdump to directly disassemble a
file .inc
Use Cortex-M settings as default, but provide the flexibility to
reuse the script for any other target CPU.

rp2040-core0.cfg configuration file was intended for a special adapter
which selects a SWD multidrop target on its own. This means
that rp2040-core0.cfg is totally unusable with a standard SWD
adapter. The file was marked as deprecated in 0.12 release.
The reworked rp2040.cfg can be restricted to use just one core:
openocd ... -c 'set USE_CORE 0' -f target/rp2040.cfg
Remove the obsoleted config.

Cortex-M support for SMP multicore targets.
This SMP implementation unlike older ones does not act
on the first halted target found. It polls targets
until a SMP group is finished and stores eventual
'halted' events instead of emitting them. As soon as polling
of a group is done, poll proceeds with SMP related tasks.
This approach improves detection of a reason why debug
stopped - a correct reason is detected for all targets,
not only for the first found.
Drawback: SMP target group should be defined in the same
order as the targets were defined.
Obsolete gdb 'J' packet/smp_gdb command core switching is not implemented,
use with rtos hwthread.
Only one core is resumed if debug_execution is requested.
Some ideas taken from Graham Sanderson's [4936]
and src/target/aarch64.c
Added error checking of armv7m_restore_context().

When pointer authentication is enabled, some upper bits of the link
register (LR[63:VA_SIZE]) are used to store a signature. Therefore, GDB
need to remove the signature to get backtraces.
GDB has support of pointer authentication. When pointer authenticaion is
enabled, GDB requests 8-bytes mask to the target to remove the
signature. mask[63:VA_SIZE] should be all set and mask[VA_SIZE-1:0]
should be all cleared. GDB removes the signature by addr&~mask or
addr|mask.
I added a feature to provide the mask for pointer authentication.
