Snap a value to nearest grid slice, using ceil.

Example: if you have an interval gap of `5` and a position of `12`... you will snap to `15`.
As will `14` snap to `15`... but `16` will snap to `20`.

@function Phaser.Math.Snap.Ceil
@since 3.0.0

@param {number} value - The value to snap.
@param {number} gap - The interval gap of the grid.
@param {number} [start=0] - Optional starting offset for gap.
@param {boolean} [divide=false] - If `true` it will divide the snapped value by the gap before returning.

@return {number} The snapped value.
