By using an mpsc queue for each iodev, the iodev itself is shareable across
contexts. Since its lock free, submits may occur even from an ISR context.
Rather than a fixed size queue, and with it the possibility of running
out of pre-allocated spots, each iodev now holds a wait-free mpsc
queue head.
This changes the parameter of iodev submit to be a struct containing 4
pointers for the rtio context, the submission queue entry, and the mpsc
node for the iodevs submission queue.
This solves the problem involving busy iodevs working with real
devices. For example a busy SPI bus driver could enqueue, without locking,
a request to start once the current request is done.
The queue entries are expected to be owned and allocated by the
executor rather than the iodev. This helps simplify potential
tuning knobs to one place, the RTIO context and its executor an
application directly uses.
As the test case shows iodevs can operate effectively lock free
with the mpsc queue and a single atomic denoting the current task.

Introduce new USB Mass Storage Bulk-Only Transport implementation
written from scratch. Main goal behind new implementation was to
separate USB and SCSI parts as clearly as possible.
Limited set of SCSI disk commands is implemented in separate source code
file that is internal to USB device stack. While it should be possible
to use the SCSI implementation by other components there is currently no
other user besides USB MSC and therefore SCSI header is kept private.

Enabling TLS increases stack usage by a small amount as that is where any
TLS variables are stored. When enabled, this sample ends up overflowing the
512-byte subscriber task stack and the IDLE_STACK_SIZE consumer stacks
Replace the fixed 512-byte subscriber stack allocation with
CONFIG_MAIN_STACK_SIZE so that it adopts a value controlled by the
configuration in case it needs to be adjusted further.
Increased CONFIG_IDLE_STACK_SIZE to 1024 to provide more space in each
consumer stack.

Picolibc is enough faster than the minimal C library that the zbus
benchmark will likely complete in well under 10ms on qemu_nios2. As this
target cannot provide a clock at higher resolution than the system tick, we
need to increase that rate to get a non-zero runtime for this benchmark.
Add new nios2-specific config variables that change the
CONFIG_SYS_CLOCK_TICKS_PER_SEC value, leaving all other platforms using the
standard value. We cannot just increase it for every platform as
qemu_arc_hs6x fails with a 1kHz rate.

The CP app sends PD a "command" and the PD responds to it. Some times,
the PD has something that it wants to tell the PD which it does so in
response to POLL command. Both CP and PD apps need a way to exchange
these info over the OSDP bus. To archive this we will introduce what are
called "events" that allow the PD app to enqueue and CP app to get
notified.
This is analogous to the incumbent "commands" abstraction where, the CP
app enqueues a command and the PD app gets notified of it.
