GPU: Added sampler information structures (TSC)

Implement Pull #3043 from citra: appveyor: Determine dlls to include in package programmatically

Minor changes to VI, PL, HID, and AUDREN

GPU: Added code to unswizzle textures and ported the surface viewer from citra

Service/sockets: add bsd:s, nsd:a, nsd:u services

TODO: A shader may not use all of these textures at the same time, shader analysis should be performed to determine which textures are actually sampled.

Allow unswizzling of DXT1 textures.

arm_dynarmic: Fix timing

GPU: Added viewport registers to Maxwell3D's reg structure.
