This PR bumps windows-rs to the latest 0.51 version.
There are some new patterns to deal with optional out params that windows isn't handling in a very elegant way, e.g. options of options of mutable pointers where the difference between None and Some(null_mut()) is not particularly evident, so some helper functions to deal with these cases should be added and applied:
out_param for pre-allocated out parameters
try_out_param for pre-allocated out parameters in a fallible function
out_ptr for out pointers allocated by the function itself
try_out_ptr for out pointers allocated by a fallible function
Example of usage:
let desc = try_out_param(|&mut out| device_and_swap_chain.GetDesc(out))?;
