Logging - Customizable backends

gl_rasterizer: Only set cull mode and front face if enabled.

GPU: Don't try to parse the depth test function if the depth test is disabled and use only the least significant 3 bits in the depth test func

GPU: Implemented MUFU suboperation 8, sqrt.

Some games set the full GL define value here (including nouveau), but others just seem to set those last 3 bits.

GPU: Implemented the depth buffer and depth test + culling

GPU: Fixed the index offset and implement BaseVertex when doing indexed rendering.

GPU: Remove unmapped surfaces from the rasterizer cache and fix our nvmap::Free behavior.

GPU: Directly copy the pixels when performing a same-layout DMA.

This fixes Stardew Valley.

GPU: Ignore invalid and disabled textures when drawing.

This behavior is confirmed by reverse engineering.

GPU: Corrected the size of the MUFU subop field, and removed incorrect "min" operation.

GPU: Implement the RGBA32_UINT rendertarget format.

gl_shader_decompiler: Implement predicate NotEqualWithNan.

Rewrite the OpenGL rasterizer cache
