This reverts commit 1b0a95e0ee.
Reason for revert: breaking g3, other downstream expectations
Original change's description:
> Omit inner join geometry when possible
>
> There is some relatively cheap math we can do to determine easy cases
> when the inner join geometry can be skipped. This CL is not
> comprehensive in that there may be other cases where we can skip the
> geometry.
>
> Only handling miter joins in this CL - the other join types can likely
> have similar logic, but will require a bit more computation to compute
> the inner (reflected) miter point.
>
> Misc notes:
> - Added SK_LEGACY_INNER_JOINS ifdef in the event that clients depend on
> the old behavior.
> - Modified stroker to track "previous previous" point, which is the
> start point of the previous line segment.
