Fix freeze on startup

[jie65535]

Description

On some devices, after starting the server and displaying ‘Loading Grasscutter’, there is no further action. The CPU usage is shown as 0% in the task manager.

By adding logs, I found that ResourceLoader.loadResources() will be executed during static loading, and all resources will be loaded simultaneously using parallel().

The specific calling path is: Grasscutter static init -> Utils.startupCheck() -> DataLoader.checkAllFiles() -> generateGachaMappings() -> Tools.createGachaMappings(path) -> ResourceLoader.loadResources() -> parallel() -> Freeze.

If parallelism is removed, it can be loaded normally, so I wonder if the thread pool has not been started during static initialization? Causes the parallel method to not continue?

Therefore, I adjusted the loading order, placed the generation logic after resource loading, and deleted the resource loading step during generation.
