std: Clamp max read/write sizes on Unix
Turns out that even though all these functions take a `size_t` they don't actually work that well with anything larger than the maximum value of `ssize_t`, the return value. Furthermore it looks like OSX rejects any read/write requests larger than `INT_MAX - 1`. Handle all these cases by just clamping the maximum size of a read/write on Unix to a platform-specific value. Closes #38590
