Let's not pretend in 2022 that it needed things from rosalina sysmodule - it did not. This moves 3DSX loading from Rosalina to Loader, and also removes all the dependencies Loader had to other Luma3DS components (if kernel ext. is missing, a default config will be used). This means that, as long as you replace Loader to the one in here, you will be able to properly load 3DSX files. Changes: - hb:ldr is now hosted in loader - hb:ldr LoadProcess, PatchExHeaderInfo, DebugNextApplicationByForce: all removed - fix a bug where some malformed 3DSX files were not rejected - grant access to CONFIG11 registers to 3DSX homebrew - move dirty homebrew chainload (when HM. isn't loaded nor loadable) to pm - pm:dbg (ext.) PrepareToChainloadHomebrew: removed
