This patch implements support for emission of following DWARFv5 macro forms

1. DW_MACRO_start_file
2. DW_MACRO_end_file
3. DW_MACRO_define_strp
4. DW_MACRO_undef_strp.

Corresponding dumping of section contents will be done in separate patch[filing review soon to have better discussion]. This is based on premises that, existing llvm-dwarfdump macro dumping requires refactoring to accommodate macro section dumping. That may take time.

Testing: I've tested/verified dumping of this debug_macro section using OBJDUMP and checked the corresponding macro expansion using LLDB and GDB.
