gl_shader_decompiler: Implement TEX, fixes for TEXS.

gl_shader_decompiler: Implement RRO as a register move.

Services/nvdrv: add '/dev/nvhost-nvdec' device

Kernel/Threads: A thread waking up by timeout from a WaitProcessWideKey may already have an assigned lock owner.

GPU: Implemented the DXN1 (BC4) texture format.

Kernel/Threads: A thread waking up by timeout from a WaitProcessWideKey may already have an assigned lock owner.

This situation may happen like so:
Thread 1 with low priority calls WaitProcessWideKey with timeout.
Thread 2 with high priority calls WaitProcessWideKey without timeout.
Thread 3 calls SignalProcessWideKey
- Thread 2 acquires the lock and awakens.
- Thread 1 can't acquire the lock and is put to sleep with the lock owner being Thread 2.
Thread 1's timeout expires, with the lock owner still being set to Thread 2.

Service/time: implement posix time to calendar conversion

Kernel/SVC: Corrected the behavior of svcSetThreadCoreMask for core values -2 and -3.

gl_rasterizer_cache: Implement PixelFormat RGBA16F.

Also added some proper error handling.

Shaders: Implemented reading the gl_InstanceID and gl_VertexID variables in the vertex shader.
