搜索 Java 时缓存 Java 信息

[Glavo]

之前我们依靠读取 release 文件加速读取 Java 信息。但是 release 文件包含的信息较少，而且我们无法从 release 文件中得知该 Java 是否能正常工作，所以可能会造成游戏无法启动的问题。

本 PR 调整了读取 Java 信息的机制，现在 HMCL 总是通过运行 Java 来获取信息。为了降低开销，我们现在使用一个缓存文件来缓存读取到的 Java 信息。

Pull Request Overview

This PR refactors Java detection and information retrieval to improve reliability by always running Java executables to obtain version information, rather than relying on potentially incomplete release files. To minimize performance overhead, a caching mechanism is introduced that stores Java information in a cache file (javaCache.json).

Key changes:

• Introduced caching system for Java information with version-aware cache file management
• Refactored Java search logic into a dedicated Searcher class
• Modified JavaRepository interface to return Collection<Path> instead of Collection<JavaRuntime>
