[clang][DebugInfo] Attach DW_AT_default_value to template arg metadata regardless of DwarfVersion
**Summary**
Starting with DWARFv5, DW_AT_default_value can be used to indicate
that a template argument has a default value. With this patch Clang
will attach the attribute to the debug metadata regardless of version.
In a follow-up patch we will change llvm to emit this attribute in
earlier versions of DWARF, unless compiling with -gstrict-dwarf.
**Details**
* Previously the DwarfVersion check in CGDebugInfo was inconsistent:
For non-type template arguments we attached the attribute to the debug
metadata in DWARFv5 only. Whereas for type template arguments we didn't
have such a version restriction. With this patch we attach the attribute
regardless of DWARF version (and instead offload the check to the AsmPrinter
in a future patch).
