Subject: [PATCH 31/63] selftests-dyndbg: add comma_terminator_tests

New fn validates parsing and effect of queries using combinations of
commas and spaces to delimit the tokens.

It manipulates pr-debugs in builtin module/params, so might have deps
I havent foreseen on odd configurations.

- skip comma tests if no builtins
