When we generate split dwarf with -fdebug-types-section we will have
.debug_types.dwo sections. These go into TU Index when we run llvm-dwp. BOLT was
not handling DWP input correctly with this section.

Added support for handling it when DWP output or DWP is output for DWARF4. For
DWARF5 it just handles it as an input for now.
