This patch adds support for template arguments of `clang::TemplateArgument::ArgKind::StructuralValue` kind (added in https://github.com/llvm/llvm-project/pull/78041). These are used for non-type template parameters such as floating point constants. When LLDB created `clang::NonTypeTemplateParmDecl`s, it previously assumed integral values, this patch accounts for structural values too. Anywhere LLDB assumed a `DW_TAG_template_value_parameter` was `Integral`, it will now also check for `StructuralValue`, and will unpack the `TemplateArgument` value and type accordingly. We can rely on the fact that any `TemplateArgument` of `StructuralValue` kind that the `DWARFASTParserClang` creates will have a valid value, because it gets those from `DW_AT_const_value`.
