[DWARF] Fix redundant DW_AT_ prefix in HANDLE_DW_AT definition for `INTEL_other_endian` (#145336)

The prefix 'DW_AT_' is automatically added by macro expansion in
consumers of Dwarf.def. Having it explicitly in the macro argument
results in duplicated naming such as DW_AT_DW_AT_INTEL_other_endian.
