Richard Smith dea290db81 Only lower files we are going to emit. (#7611) 
Move `--output-last-file-only` and output filename synthesis logic out
of the general-purpose compile driver and into the `carbon compile`
subcommand, which is the only thing that should be using them. Track on
CompilationUnit whether it is being lowered, or whether it exists only
to be imported into other units.

`carbon compile` now never lowers inputs that it discovered for itself,
only inputs that were specified on the command line. In particular, it
doesn't lower (and throw away the result of lowering) the prelude any
more. This makes the toolchain tests about 10% faster in my crude
measurements.

Also, we now do not create a clang `CodeGenerator` for input files that
we are not lowering, similarly saving compilation time for units that
exist only to be imported, not lowered.

One minor change: we use the same mechanism to determine whether an
input is being lowered and to determine what the output filename is.
This means that `--phase=lower` and `--phase=optimize`, which lower but
don't produce an output file, still need an output filename to be
specified now in some cases. Given those are just debugging tools, I
think that's fine.
