fix: dts lost in re-compilation if save file with same content

[PeachScript]

修复存在持久缓存已存在且重复保存某个文件但不修改内容时，.d.ts 不会生成的问题，另外修改 .tsbuildinfo 文件的位置强行让存量项目的 tsc 缓存失效实现缓存重建。

原因是 tsc 的 incremental 模式不会生成未变更的文件，father 使用持久缓存补齐这些文件，但缓存 key 不是依据内容哈希而是文件修改时间，所以在文件重复保存时，tsc 认为文件没有变更（应该是以哈希判断？）所以不会生成，father 又从持久缓存中找不到（以时间戳查找）对应内容无法补齐文件，最终导致 .d.ts 丢失。

解法是 father 对 .d.ts 的缓存 key 改为内容哈希，确保重复保存时也能命中。
