/**
 * Internal function to process the horizontal separation of a physics body from a tile.
 * It updates the body's left or right blocked flags based on the direction of separation,
 * moves the body by the separation amount along the x-axis, updates its center, and then
 * either zeroes the horizontal velocity or applies a bounce depending on the body's bounce coefficient.
 *
 * @function Phaser.Physics.Arcade.Tilemap.ProcessTileSeparationX
 * @since 3.0.0
 *
 * @param {Phaser.Physics.Arcade.Body} body - The Body object to separate.
 * @param {number} x - The x-axis separation distance, in pixels. A negative value indicates the body is blocked on the left; a positive value indicates it is blocked on the right.
