Add a target option for selecting a DWARF version
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
