97ed5b8afb Ruby: Improvments to splat flow
- Only step through a `SynthSplatParameterElementNode` when there is a splat parameter
  at index > 0.
- Model read+stores via `SynthSplatArgumentElementNode` as a single read-store
  step in type tracking.

5a6a52b767 Ruby: Use fewer SynthSplatArgumentElementNodes
In cases such as

    def f(x, *y); end

    f(*[1, 2])

we don't need any `SynthSplatArgumentElementNodes`. We get flow from the
splat argument to a `SynthSplatParameterNode` via `parameterMatch`, then
from element 0 of the synth splat to the positional param `x` via a
read step.

We add a read step from element 1 to `SynthSplatParameterElementNode(1)`.
From there we get flow to element 0 of `*y` via an existing store step.
