Subject: resulttool: Add option to dump all ptest logs

Adds an option to dump all the ptest logs to individual files in a
specified directory. If multiple test runs are present, the
'--prepend-run' argument will create separate directories for each test
run under the target directory and put the logs there to prevent each
test run from clobbering the others.

[YOCTO #13331]
