Enable HMCL to export jstack dump file 让 HMCL 能够导出游戏运行栈文件 (#2582)
* Enable HMCL to create game thread dump while game is running * Fix checkstyle * Hide accessToken * Code cleanup * Code cleanup * Enhance I18N and declare the charset (UTF-8) of output file * Inline variables * Update the modifier of org.jackhuang.hmcl.game.GameDumpCreator#writeDumpHeadTo from public to private * Refactor * Add license for GameDumpCreator, remove support for Java 8 * Remove unnecessary Arrays.copyOf * Fix checkstyle * Use system charset to read the inputstream from JVM * opt GameDumpCreator * retry on failed attach to vm * update GameDumpCreator * Opt GameDumpCreator * Fix * Include BCIG * Use BCIG to get PID. * Fix. * Fix again. * Code cleanup. Fix bugs. --------- Co-authored-by: Glavo <zjx001202@gmail.com>
