Reals were mostly handled, but this PR adds storage of them. It also switches a little towards the FloatingPointType semantic from TokenizedBuffer. While real literals like `1.0` were handled, the type literals were not. This just adds `f64`, similar to how I also only support `i32`. The String type literal wasn't used, so I've added support in lexer and parser. Per discussion with @zygoloid String might be renamed based on the newer type literal plan, but it's still String in explorer and the design, so this is just consistent. The builtin_types.carbon tests the three basic types that are there right now. The test is added to both parser and semantics so that it's clear what the state is in both stages.
