fixes to the previous commit

 * CompileStep: Avoid calling producesPdbFile() to determine whether the
   option should be respected. If the user asks for it, put it on the
   command line and let the Zig CLI deal with it appropriately.
 * Make the namespace of `std.dwarf.Format.dwarf32` no longer have a
   redundant "dwarf" in it.
 * Add `zig cc` integration for `-gdwarf32` and `-gdwarf64`.
 * Toss in a bonus bug fix for `-gdwarf-2`, `-gdwarf-3`, etc.
 * Avoid using default init values for struct fields unnecessarily.
 * Add missing cache hash addition for the new option.
