Converts the service manager from a global into an instance-based
variable.

* core, main.h: Abort on 32Bit ROMs

* main.cpp: Fix Grammar

Also moved the GPU MemoryManager class to video_core since it makes more sense for it to be there.

 - Deleted GetStatus() because it wasn't used anywhere outside of Core::System.
 - Fixed design flaw where the message bar status could be set despite the game being stopped.

Optimized messages that were repetitive and added ability for core errors to specify more details optionally.

- Made LoadKernelSystemMode return a pair consisting of a system mode and a result code (Could use review).
- Deleted ErrorOpenGL error code in favor of just having ErrorVideoCore.
- Made dialog messages more clear.
- Compared archive ID in fs_user.cpp to ArchiveIdCode::NCCH as opposed to hex magic.
- Cleaned up some other stuff.

Now based on std::chrono, and also works in terms of emulated time
instead of frames, so we can in the future frame-limit even when the
display is disabled, etc.

The frame limiter can also be enabled along with v-sync now, which
should be useful for those with displays running at more than 60 Hz.

More ergonomic to use and will be required for upcoming changes.

Add error popup when citra initialization failed

The VFP registers are 64 bits each, and there are 32 of them.

The TLS area for thread T with id Ti is located at TLS_AREA_VADDR + (Ti - 1) * 0x200.
This allows some games like Mario Kart 7 to continue further.
