Feature request: convenience macros/functions

[Razordor]

Motivation

certain macros such as MAKEINTRESOURCE, and GET_X_LPARAM aren't in windows-rs which would make using functions like LoadImage inconvenient. Adding convenience macros would make useability easier.

Drawbacks

Drawback could be further bloating the crate

Rationale and alternatives

convenience macros could be const functions, or declarative macros.

...and #921 and #1205 and #1445...

I'm beginning to think we should do something about this. Maybe make a windows-rsEx crate? 😆

Yep, a dedicated crate for macros seems appropriate.
