This patch adds support for dumping `DW_MACRO_define_strx`, `DW_MACRO_undef_strx` in llvm-dwarfdump. These forms are currently supported only in `debug_macro` section.

- Added test containing multiple CUs(2 CU) contributing to macro section via `DW_MACRO_define_strx` form. llvm-dwarfdump is able to parse/dump contents correctly.

This patch is separated from D78500 <https://reviews.llvm.org/D78500> based on feedback from @dblaikie , @ikudrin, Thanks for this!

Support for these forms in a `debug_macro.dwo` section will be done in a separate patch.
