Add UI support for extracted NCA folders

svc: Add a stub for UserExceptionContextAddr.

gl_rasterizer: Get loose on independent blending.

gl_rasterizer_cache: Loosen things up a bit.

gl_shader_decompiler: Implement LOP instructions.

gl_shader_decompiler: Implement register size conversions for I2I and I2F.

gl_shader_decompiler: Implement LOP32I LogicOperation PassB.

gl_shader_gen: Set position.w to 1.

Qt: Removed the Registers widget.

It was crashing and nobody actually uses this.

GPU: Partially implemented the Maxwell DMA engine.

GPU: Implemented the iadd32i shader instruction.

Only tiled->linear and linear->tiled copies that aren't offsetted are supported for now. Queries are not supported. Swizzled copies are not supported.

hid: Update all layouts and only show handheld as connected, fixes libnx input for P1_AUTO

gl_shader_decompiler: Implement saturate for float instructions.

GPU: Convert the gl_InstanceId and gl_VertexID variables to floats when reading from them.

This corrects the invalid position values in some games when doing attribute-less rendering.

GPU: Implement the ISET family of shader instructions.

GPU: Stub the SSY shader instruction.

gl_shader_decompiler: Implement SHR instruction.

gl_shader_decompiler: Implement IADD instruction.

This instruction tells the GPU where the flow reconverges in a non-uniform control flow scenario, we can ignore this when generating GLSL code.
