Subject: [PATCH] Update BaseObject.ts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`String(value)`  即便是对象本身没有实现 `toString()` 方法的情况下，性能都要低几倍
可参考 https://tc39.es/ecma262/multipage/text-processing.html#sec-string-constructor
会在`toString()`之前做了多个检查
而 DragonBones 中所有class，都实现了 `toString()` 方法，性能更高
毕竟这是一个大量调用的方法
