The production version of the nRF54H20 SoC is now available, so remove
the initial Engineering B (EngB) preview version.

Add an alternate message output option in which messages are
ended with an additional zero data byte with marker and timestamp.
Can be used to maintain compatibility with certain decoders.

There are many places where source_id is retrieved and it
depends on runtime filtering being enabled. So far it was
all exposed but lets encapsulate that into a helper function.

Currently we can assume that flpr and ppr cores are always owned by
cpuapp. In that case, cpuapp (which processes ETR buffer content) has
access to the memory where logging strings from ppr and flpr are
located. Those strings do not need to be appended to the message
which is written to the STM (in case of standalone configuration).
This approach reduced logging time, e.g. logging a message with
one argument takes 1.8us on cpuapp and 6.3us on cpurad.
This setting applies only to the case when cpuapp is the owner
of those co-oprocessors and shall be updated if that becomes
configurable but currently there are no means to detect core
owner.

Demultiplexer was not ready to handle case when log message was
incomplete which was followed by other log messages. Such scenario
could occur if there was a fault that happen during logging of
a message. In that case incomplete message was followed by valid
messages (fault report) and this fault report was not handled
because processing was blocked waiting for completion of a
message which preceeded fault report.
Since it is expected that some messages may be incomplete a
garbage collection mechanism is added. When start of a message is
received timestamp is logged and list of incomplete messages
is checked for 'old' messages which persist in incomplete state
for long. When message timeouts it is closed and marked as
invalid. It unblocks processing of following messages.

write_data function which was writing to STMESP data registers was
starting by writing words and tail was written using byte access.
However, RISCV core does not support unaligned access and on Cortex-M33
even if supported it is faster to do aligned access. Reworked
write_data to start first by writing data using byte or half word
access until data pointer is word aligned, then word access is used
and finally tail is written using byte or half word access.

Add support for standalone mode where data written to STMESP is
decoded on chip to a human-readable strings.

Add module which demultiplexes stream of log message which are
encoded into STPv2 stream by log_frontend_stmesp. There are 3 types of
messages that can be present in the stream:
- Log message (starts with DMTS32, followed by Dx and closed by FLAG)
- Tracepoint (FLAGTS or DMTS32)
- STM HW event (DMTS8 on 0x80 master and 0x00 channel)

As there are more frontends coming in the future move existing
frontend to the dedicated directory (like backends).
