Exported header oftenly used when creating a logging
backend that inpects the log 'stream'.
Enables use in external Zephyr modules implementing the
logging backend interface.

MISRA-C Rule 5.3 states that identifiers in inner scope should
not hide identifiers in outer scope.
The log output instances all named "log_output" in backends
collide with the "log_output" parameter of various functions.
This renames the variables in the backends to make them
more descriptive. Same goes for the buffers for some of
these instances as they are all named "buf", and "hostname"
being used in the network backend, so they are renamed.
There are a few places where variables are overriden within
an inner scope (e.g. inside loop and if block) so they are
also renamed.

Replace DT_CPU_CLOCK_FREQUENCY with a PATH based reference to cpu@0
(DT_PATH(cpus, cpu_0)) and than getting the clock_frequency property:
DT_CPU_CLOCK_FREQUENCY -> DT_PROP(DT_PATH(cpus, cpu_0), clock_frequency)
This lets us remove DT_CPU_CLOCK_FREQUENCY from dts_fixup.h.

The log_backend_swo used system clock frequency
as a base for SWO clock calculation. This commit
corrects that by obtaining the needed value from DTS.
