gl_shader_decompiler: Implement ISETP_IMM instruction.

GPU: Implement sampling multiple textures in the generated glsl shaders.

 gl_shader_decompiler: Implement LD_C instruction.

All tested games that use a single texture show no regression.

Only Texture2D textures are supported right now, each shader gets its own "tex_fs/vs/gs" sampler array to maintain independent textures between shader stages, the textures themselves are reused if possible.

* add IoctlCommands with their params in nvidia_ctrl_gpu.h

* add function related to the changes done previously

* fix clang-format

* delete trailing whitespace

* correct mistake

Stub SetConnectionConfirmationOption, GetPseudoDeviceId

gl_shader_decompiler: Fix un/signed mismatch with SHL.

maxwell_to_gl: Implement WrapMode Mirror.

GPU: Allow the usage of RGBA32_FLOAT and RGBA16_FLOAT in the texture copy engine.

GPU: Implemented the R11FG11FB10F texture and rendertarget formats.

* GDB Stub should work now.

* Applied clang-format.

* Replaced htonll with swap64.

* Tidy up.

They're not compressed.
