armv7m_trace: stop getting traces from adapter at exit
If OpenOCD is reading trace data from the target, at exit it
should stop the adapter to gather data, but should left the target
still producing them.
Add a helper in armv7m_trace to disable the adapter's trace and
call it during OpenOCD teardown.
This also provides a workaround for an issue in the firmware of
ST-Link V3 till version V3J7. If the SWD connection is closed when
trace is active, at following connection the trace does not work
anymore.
