GPU: Added asserts to our code for handling the QUERY_GET GPU command.

service: Move logging macros over to the new fmt-compatible ones

renderer_opengl: Silence a -Wdangling-else warning in DrawScreenTriangles()

Service/FS: implement IFileSystem::RenameFile

GPU: Support multiple enabled vertex arrays.

This is based on research from nouveau. Many things are currently unknown and will require hwtests in the future.
This commit also stubs QueryMode::Write2 to do the same as Write. Nouveau code treats them interchangeably, it is currently unknown what the difference is.

Kernel: Reworked the new kernel synchronization primitives.

 Nvdrv/nvhost-as-gpu: Implemented the ioctl REMAP command. 

Nvdrv: Assert when receiving an unimplemented ioctl in the nv* handlers.
