Add a target option for selecting a DWARF version

Browse source 
Certain platforms need to limit the DWARF version emitted (oxs, *bsd). This
change adds a dwarf_version entry to the options that allows a platform to
specify the dwarf version to use. By default this option is none and the default
DWARF version is selected.

Also adds an option for printing Option<u32> json keys
