Chuanqi Xu 52770d83bf [Serialization] Don't pack bits for the function scope index of ParmVarDecl
Close https://github.com/llvm/llvm-project/issues/76443

Previously we assume the bits of the function scope index of ParmVarDecl
won't exceed 8. But this is a misreading. See the implementation of
`ParmVarDecl::getParameterIndex()`, which may
exceed the size of the normal bitfield. So it may be better to not
pack these bits.
