Mainly concerns to building with Ninja, as that's what I tested it with.
Originally it would only prepend the first path with `/external:I`,
however all paths in the list have to be prepended with `/external:I`.
The MS documentation seems to support this, as it makes no mention of it
accepting a list.
This is probably the worst way to implement this, I am unfamiliar with
CMake.
Previously, EFB copies would be in the middle of other objects, as objects were only split on primitive data. A distinct object for each EFB copy makes them easier to spot, but does also mean there are more objects that do nothing when disabled (as disabling an object only skips primitive data, and there is no primitive data for EFB copies).
This also adds the commands after the last primitive data but before the next frame as a unique object; this is mainly just the XFB copy. It's nice to have these visible, though disabling the object does nothing since only primitive data is disabled and there is no primitive data in this case.

Before e1e3db13ba
the ControllerInterface m_devices_mutex was "wrongfully" locked for the whole Initialize() call, which included the first device population refresh,
this has the unwanted (accidental) consequence of often preventing the different pads (GC Pad, Wii Contollers, ...) input configs from loading
until that mutex was released (the input config defaults loading was blocked in EmulatedController::LoadDefaults()), which meant that the devices
population would often have the time to finish adding its first device, which would then be selected as default device (by design, the first device
added to the CI is the default default device, usually the "Keyboard and Mouse" device).
After the commit mentioned above removed the unnecessary m_devices_mutex calls, the default default device would fail to load (be found)
causing the default input mappings, which are specifically written for the default default device on every platform, to not be bound to any
physical device input, breaking input on new dolphin installations (until a user tried to customize the default device manually).
Default devices are now always added synchronously to avoid the problem, and so they should in the future (I added comments and warnings to help with that)
