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.

ef842dda2a Fix extremely obnoxious race-cond+uninit handle bug
This is mostly a libctru bug (well, sort of).

This can only happen to built-in sysmodules, and to
processes waiting for err:f, that fail to obtain
handles through svcConnectToPort first try; and only
prior to 11.0.

Prior to fw 11.0, kernel didn't zero-initialize output
handles, and thus the output handle gets filled with
junk (leaked kernel stack data) in case of failure.
Libctru does not account for this, and closes such
handles anyway (in srvInit, errfInit, and possibly
more).

The problem is that, in our case, that garbage was
equal to 0x8000, actually a valid handle, in fact
the first handle to be created (and not closed) in
a process... a handle to KAddressArbiter.

Accidentally closing this handle resulted in one or
more KIPs spin-waiting and starving core1, resulting
in an inability to boot.

We fix this simply by replicating what recent k11 does,
in kext (for svcConnectToPort). For srvGetServiceHandle,
add two layers of safety.

b71dedccfc Full support for fw >= 6.x (tested)
Virtually full support for 5.x except that svcUnmapProcessMemoryEx will be forwarded to svcUnmapProcessMemory (both are equivalent for up to 64MB chunks)
