Install a .desktop file to make citra-qt launchable from DE menus

PTM: Changed the ptm services  to be like the IR, HID, and APT services.

GPU: add more fine grained profiling for vertex shader and rasterization

Core/Memory: Add TLS support for creating up to 300 threads

Thread: Remove the idle thread

Core/Scheduling: Prepare the new priority in the thread queue when svcSetPriority is called

vfp: Handle flush-to-zero mode.

dyncom: Stub MCRR and MRRC

Instead just use nullptr to represent no thread is active.

Core/HLE: Implemented the SVCs GetProcessId and GetProcessIdOfThread

IR, HID, and APT services.

There's no other coprocessor outside the VFP (which has its own VMOV variants) in which the MPCore can send/retrieve data from.
Stubbed so citra won't crash and burn on the odd chance someone actually tries to use these.

NWM_UDS: Fix a typo in the nwm service port name

Thread: Correctly set main thread initial stack position

Implement I4 texture format

@neobrain, could you confirm that this is correct?

It's been tested with various different games and fixes different textures, including in Animal Crossing, Kirby Triple Deluxe, and SMB3D.

Fix crashes due to un-initialized GSP shared memory

Give each emulated thread it's own TLS memory

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.

This works around crashes related to GSP/HID/etc. shared memory blocks
having garbage values. The proper fix requires proper management of
mapped memory blocks in the process.
