io_uring/mock: add basic infra for test mock files
io_uring commands provide an ioctl style interface for files to implement file specific operations. io_uring provides many features and advanced api to commands, and it's getting hard to test as it requires specific files/devices. Add basic infrastucture for creating special mock files that will be implementing the cmd api and using various io_uring features we want to test. It'll also be useful to test some more obscure read/write/polling edge cases in the future.
