cocos3.8.7中支持颜色混合

仅在cocos3.8.7中测试。
两种方法。
1.可以修改源码的情况下，修改BlendMode.ts文件的apply函数。
public static apply(node: Node, blendMode: BlendMode) {
let f = factors[<number>blendMode];
node.components.forEach(component => {
if (component instanceof UIRenderer) {
component["_srcBlendFactor"] = f[0];
component["_dstBlendFactor"] = f[1];
}
})
}2.不修改源码，覆盖GObject的setup_beforeAdd方法。随意一个脚本中添加并调用Init();
public static init() {
const factors = [
[gfx.BlendFactor.SRC_ALPHA, gfx.BlendFactor.ONE_MINUS_SRC_ALPHA], //normal
[gfx.BlendFactor.ONE, gfx.BlendFactor.ONE], //none
[gfx.BlendFactor.SRC_ALPHA, gfx.BlendFactor.ONE], //add
[gfx.BlendFactor.DST_COLOR, gfx.BlendFactor.ONE_MINUS_SRC_ALPHA], //mul
[gfx.BlendFactor.ONE, gfx.BlendFactor.ONE_MINUS_SRC_COLOR], //screen
[gfx.BlendFactor.ZERO, gfx.BlendFactor.ONE_MINUS_SRC_ALPHA], //erase
[gfx.BlendFactor.ZERO, gfx.BlendFactor.SRC_ALPHA], //mask
[gfx.BlendFactor.ONE_MINUS_DST_ALPHA, gfx.BlendFactor.DST_ALPHA], //below
[gfx.BlendFactor.ONE, gfx.BlendFactor.ZERO], //off
[gfx.BlendFactor.SRC_ALPHA, gfx.BlendFactor.ONE_MINUS_SRC_ALPHA], //custom1
[gfx.BlendFactor.SRC_ALPHA, gfx.BlendFactor.ONE_MINUS_SRC_ALPHA], //custom2
[gfx.BlendFactor.SRC_ALPHA, gfx.BlendFactor.ONE_MINUS_SRC_ALPHA], //custom2
];

const GObjectSetupBeforeAdd = fgui.GObject.prototype.setup_beforeAdd;
fgui.GObject.prototype.setup_beforeAdd = function (this: fgui.GObject, buffer: ByteBuffer, beginPos: number) {
GObjectSetupBeforeAdd.call(this, buffer, beginPos);
let f = factors[<number>this.blendMode];
this.node.components.forEach(component => {
if (component instanceof cc.UIRenderer) {
component["_srcBlendFactor"] = f[0];
component["_dstBlendFactor"] = f[1];
}
})
}
}
因为blend模块的相关代码没有导出，所以先这么处理。factors数组是从fgui源码中复制出来的。
_srcBlendFactor和_dstBlendFactor两个属性的cocos源码在cocos源码地址。

已经提交pr，谷主看到的话希望能合并一下。
