[unity] webgl wasmbigint 支持

[mingxxming]

unity 2023.2.20.f1c1 支持wasmbigint了。 但是puerts初始化异常
Tencent/puerts#1798

[mingxxming]

SetGlobalFunction: function (isolate, nameString, v8FunctionCallback, jsEnvIdx, callbackidx) {
callbackidx = callbackidx == undefined ? Number(jsEnvIdx >>32n) : callbackidx;
const name = engine.unityApi.UTF8ToString(nameString);
library_1.global[name] = engine.makeCSharpFunctionCallbackFunction(true, v8FunctionCallback, callbackidx);
},

同样的报错,好像和wasmbigint没关系,我也是用的unity2023.3,小版本是3,但是还是有一样的错误

自己改改，改完unity6依然可正常使用
