Do We Want to Use CFG Aliases?

[zicklag]

Just saw this TODO:

bevy/crates/bevy_winit/src/lib.rs

Lines 174 to 176 in b17f8a4

	// TODO: It may be worth moving this cfg into a procedural macro so that it can be referenced by
	// a single name instead of being copied around.
	// https://gist.github.com/jakerr/231dee4a138f7a5f25148ea8f39b382e seems to work.

If it's something we want to do we can use the cfg_aliases crate to make convenient aliases for cfg checks. It's an extra dependency, but not really because it's already used in GFX and WGPU and it's just a macro_rules macro that doesn't have any dependencies itself.

I could open a PR if that helps.

This could be pretty useful given the explosion in platform-specific cfg attributes (i.e. webgl and webgpu). Could you open a PR for this?

I've been crazy busy lately so I probably won't have time to open a PR.

It's super easy to setup, though, and here's an example of how it's used on wgpu, if anybody else wants to take a hack at it, it'd be a good beginner issue.
