Factor out `SemIR::InstNamer` and also use it when lowering to LLVM IR. Automatically name all instructions created with our `IRBuilder` based on the name computed by the `InstNamer`, and likewise name basic blocks using the label generated by the `InstNamer`. Move some of the existing naming logic out from lower into `InstNamer` so that it's also used in SemIR. In particular, we now name call instructions after their callee, or after the builtin name for calls to builtins. Computing and adding these names isn't completely free. This instruction naming is designed to be optional, so that we can turn it off for builds where the LLVM IR will only be converted to assembly and won't be seen by a human, but so far it's enabled unconditionally. We can tune that later as needed.
