file_util: Make move constructor/assignment operator and related functions noexcept 

Without this, it's possible to get compilation failures in the (rare) scenario where
a container is used to store a bunch of live IOFile instances, as they may be using
std::move_if_noexcept under the hood. Given these definitely don't throw exceptions
this is also not incorrect to add either.
