Add support for viewport_transfom_enable register

gl_rasterizer: Skip VB upload if the state is clean.

* GPU States: Implement Polygon Offset. This is used in SMO all the time.

* Clang Format fixes.

* Initialize polygon_offset in the constructor.

Implemented BRA CC conditional and FSET CC Setting

gl_shader_decompiler: Implement S2R's Y_DIRECTION

gl_shader_decompiler: Implement BFI_IMM_R

service/sm: Take std::string by const reference in UnregisterService

gl_shader_decompiler: Implement R2P_IMM

Fixed Coordinate Encodings in TEX and TEXS instructions

gl_shader_decompiler: Implement clip distances

video_core: Move morton functions out of gl_rasterizer_cache

svc: Return ERR_INVALID_ENUM_VALUE from svcGetInfo

nvdrv: Implement/stub DumpGraphicsMemoryInfo and GetStatus.

memory_manager: Do not allow 0 to be a valid GPUVAddr.

Avoids the need to create a copy of the std::string instance
(potentially allocating).

The only reason RegisterService takes its argument by value is because
it's std::moved internally.

sm: Implement RegisterService and UnregisterService

filesystem: Clear registered union paths on factory creation

Update OpenGL's backend version from 3.3 to 4.3

gl_shader_decompiler: Rename cc to condition code and name internal flags

- Used by Undertale.

shader_cache: Only lock covered instructions.

software_keyboard: Minor changes

- Fixes a bug with Undertale using 0 for a render target.

applets: Add StubApplet and use it as fallback when AppletId is not implemented
