gdb/testsuite/dwarf: use options for rnglists/loclists procs

Change how rnglists and loclists procs to align them with how procs for
aranges (and other things in the DWARF assembler) work.  Instead of
using "args" (variable number of parameters in TCL) and command-line
style option arguments, use one leading "option" parameters, used as a
kind of key/value dictionary of options parsed using `parse_options`.
