add explicit default initialization to DemangledNameInfo to remove warning (llvm#141790)

llvm#140762 introduces some
compilation warnings in `lldb/unittests/Core/MangledTest.cpp`. This
patch adds explicit default initialization to `DemangledNameInfo` to
suppress those warnings.

We only had the default initialization values to `PrefixRange` and
`SuffixRange` because they are the only _optional_ fields of the
structure.
