As discussed in D99250 <https://reviews.llvm.org/D99250> , we added a new tuning debugger DBX(D99400 <https://reviews.llvm.org/D99400>) to add some debug info customizations for DBX on AIX.

This is part of the customizations, not generating DWARF infos not matching the DWARF version.

This is for `DW_AT_alignment` attribute.

Now for DBX, we only generate this attribute when DWARF version is 5 or higher.
