Jon Ross-Perkins 4193c306a4 Add range flag settings to function files (#5558) 
Where `--no-dump-sem-ir` is used, change to `--dump-sem-ir-ranges=only`.
Otherwise, add `--dump-sem-ir-ranges=if-present` with a TODO to change
to `only`.

Note, SemIR is affected just because the extra comments change line
numbers in files where splits aren't in use.
