[clang][c++20] Fix code coverage mapping crash with generalized NTTPs (#85837)
Introduced in #78041, originally reported as #79957 and fixed partially
in #80050.
`OpaqueValueExpr` used with `TemplateArgument::StructuralValue` has no
corresponding source expression.
A test case with subobject-referring NTTP added.
