With the previous Copy{To,From}User helpers we need to actually
implement the handlers correctly. We want something that is a bit
lighter so we don't need to implement the faulting path in the syscall
handlers.
Implements a handful of helpers that just check for readable and
writable capability which can be thrown in to an assertion handler that
is zero cost in release mode.
Readable is checked by just attempting to read all bytes.
Writable is checked by attempting to read each byte and writing it back
to the same location.
Uses these helpers in x64/FD.cpp to showcase how they will be used to
detect EFAULT. Tested locally that they work correctly by writing some
small tests for the syscalls that expect EFAULT.
