Merge 3GX plugin loader fork (#1916)
This commit adds all the changes made to the 3GX plugin loader fork of Luma3DS. The most important features are:

- Add 3GX plugin loader support. New service added to rosalina: plg:ldr
- Add svcControlProcess, svcControlMemoryUnsafe and improve svcMapProcessMemoryEx (breaking change)
- Allow applications to override certain configurations depending on their needs:
    - Disable core2 thread redirection
    - Disable game patching for the next app
    - Force New 3DS speedup
    - Force next application in a specific memory mode
    - Block the opening of the Rosalina menu
- Add GDB commands to list all process handles and catch all SVC (latter is for IDA Pro as gdb client supports it)
- Other changes necessary for plugins to work properly. Please check changed files in this PR for more details.
