Use libhac for loading NSO and KIP (#1047)
* Use libhac for loading NSOs and KIPs * Fix formatting * Refactor KIP and NSO executables for libhac * Fix up formatting * Remove Ryujinx.HLE.Loaders.Compression * Remove reference to Ryujinx.HLE.Loaders.Compression in NxStaticObject.cs * Remove reference to Ryujinx.HLE.Loaders.Compression in KernelInitialProcess.cs * Rename classes in Ryujinx.HLE.Loaders.Executables * Fix space alignment * Fix up formatting
