  [lldb] Recurse through DW_AT_signature when looking for attributes (#107241)

This allows e.g. DWARFDIE::GetName() to return the name of the type when
looking at its declaration (which contains only
DW_AT_declaration+DW_AT_signature). This is similar to how we recurse
through DW_AT_specification when looking for a function name. Llvm dwarf
parser has obtained the same functionality through #99495.

This fixes a bug where we would confuse a type like NS::Outer::Struct
with NS::Struct (because NS::Outer (and its name) was in a type unit).
