sprite material v1

[Cupnfish]

Objective

The objective of this PR is to add Material functionality to the existing Sprite component, allowing users to customize the rendering pipeline of sprites by defining their own SpriteMaterial.

Solution

Two versions of the implementation are provided:

1. In this version, a new SpriteWithMaterial component is introduced. It includes a material field to specify the sprite's material tint. The SpriteWithMaterial struct is similar to the existing Sprite struct, with the addition of the material field. However, migrating from the original Sprite to SpriteWithMaterial may be inconvenient.

2. In this version, the original Sprite component is reused, and a SpriteMaterialMarke component is introduced to assist in filtering query results. The changes include adding the material field to the SpriteSheetWithMaterialBundle struct. Migrating from the original Sprite to the SpriteMaterialMarke version requires fewer code changes.
