hla/stlink: Re-order trace parameters to allow trace output file to be optional
Re-order the "trace" parameters to allow the raw capture (log) file to
be an optional feature. The clock frequency for calculating the "Async
Clock Prescalar" is always required when enabling trace processing and
is now the first "required" parameter.
The ST-Link driver is updated to use the (required parameter)
"trace_source_hz" non-zero value as the indicator of trace being
required, rather than the now optional output file descriptor being
non-NULL.
Background: This patch is groundwork for extending the OpenOCD SWO
capture to implement other (OpenOCD built-in) ITM/DWT processing where
the core trace support is required, but there is no requirement to
store raw trace data to a configured host file. By itself this patch
is almost a functional NOP, since without the other processing in
place there is no reason NOT to specify a capture file.

arm7_9: Avoid infinite loops in bulk write dispatching
Add a mandatory field in struct arm7_9_common for regular, non-optimized
memory writes. Together with the existing bulk_memory_write field, this
allows variants to select any combination of implementations for regular
and bulk writes, without risking infinite loops from accidentally using
bulk writes for implementing bulk writes.
ARM 7/9 targets may now select arm7_9_memory_write_opt as their
target.write_memory implementation, which will dispatch to
arm7_9_common.bulk_write_memory if possible, or fallback to
arm7_9_common.write_memory otherwise.
To avoid loops, bulk write implementations mustn't call any other
functions than arm7_9_write_memory_no_opt() to write memory; it will
unconditionally call arm7_9_common.write_memory. If they fail, they should
simply return error to allow the caller to fallback to regular writes.
Tested on a regular ARM7TDMI only.
