selftests/x86/lam: Add io_uring test cases for linear-address masking
LAM should be supported in kernel thread, using io_uring to verify LAM feature.
The test cases implement read a file through io_uring, the test cases choose an
iovec array as receiving buffer, which used to receive data, according to LAM
mode, set metadata in high bits of these buffer.
io_uring can deal with these buffers that pointed to pointers with the metadata
in high bits.
