[DebugInfo] Support DWARFv5 index sections. DWARFv5 defines index sections in package files in a slightly different way than the pre-standard GNU proposal, see Section 7.3.5 in the DWARF standard and https://gcc.gnu.org/wiki/DebugFissionDWP for GNU proposal. The main concern here is values for section identifiers, which are partially overlapped with changed meanings. The patch adds support for v5 index sections and resolves that difficulty by defining a set of identifiers for internal use which can represent and distinct values of both standards. Differential Revision: https://reviews.llvm.org/D75929

## The test checks that we can parse and dump a CU index section that is
## compliant to the DWARFv5 standard.

# CHECK: .debug_cu_index contents:
llvm-dwarfdump: Include unit count in DWP index header dumping And add comma separators (to be consistent with recent changes/improvements to the dumping of other section headers) while I'm here.
