[Clang] Don't assert on substituted-but-yet-expanded packs for nested lambdas (#112896)
Nested lambdas could refer to outer packs that would be expanded by a
larger CXXFoldExpr, in which case that reference could happen to be a
full expression containing intermediate types/expressions, e.g.
SubstTemplateTypeParmPackType/FunctionParmPackExpr. They are designated
as "UnexpandedPack" dependencies but don't introduce new packs anyway.
This also handles a missed case for VarDecls, where the flag of
ContainsUnexpandedPack was not propagated up to the surrounding lambda.
Fixes #112352
