Replace `SemIR::Node::GetAsFoo` and `SemIR::Node::Foo::Make` with `SemIR::Foo` class that represents a particular kind of node, with named fields. Rename `SemIR::IntegerLiteral` and `SemIR::RealLiteral` to `IntegerValue` / `RealValue` to better reflect their purpose and avoid a name collision with the corresponding `SemIR` node kinds. Remove `NodeKind::Invalid` and the `SemIR::Node` default constructor entirely, as they were not used for anything.
