[DWARF5] Replace emission of strp with stx forms in debug_macro section DW_MACRO_define_strx forms are supported now in llvm-dwarfdump and these forms can be used in both debug_macro[.dwo] sections. An added advantage for using strx forms over strp forms is that it uses indices approach instead of a relocation to debug_str section. This patch unify the emission for debug_macro section.
