reuse _tempVec2 and avoid creating new temple object

[minggo]

_calculateMovePercentDelta() just uses anchor.x and anchor.y, and will not pass it to other functions, so it is safe to reuse _moveDeltaOptions and _tempVec2.

The best solution is change the parameter from _calculateMovePercentDelta(options: MoveDeltaOptions) to _calculateMovePercentDelta(anchor: Vec2, applyToHorizontal: boolean, applyToVertical: boolean). Then even don't have to:

• define MoveDeltaOptions
• create _moveDeltaOptions
• and don't have assign _moveDeltaOptions before invoking _calculateMovePercentDelta()

But it will break the compatibility, as _calculateMovePercentDelta() is a protected function.
