Determine msrv for every standalone bevy_* crate.

[Brezak]

Objective

As was pointed out in #13183, bevy_mikktspace is missing it's msrv from it Cargo.toml. This promted me to check the msrv of every bevy_* crate. Closes #13183.

Solution

• Call cargo check with different rust versions on every bevy crate until it doesn't complain.
• Write down the rust version cargo check started working.

Testing

• Install cargo-msrv.
• Run cargo msrv verify.
• Rejoice.

---

Changelog

Every published bevy crate now specifies a MSRV. If your rust toolchain isn't at least version 1.77.0 You'll likely not be able to compile most of bevy.

Migration Guide

If your rust toolchain is bellow version`1.77.0, update.

I spent too much time on this graph. I need it immortalized somewhere.

Loading

Every bevy workspace crate, it's bevy dependencies and it's msrv.

[mockersf]

generally not in favor of this. It doesn't make sense to track a MSRV for some of those crate as they don't really make sense as a standalone crates, so it just means we will have more things to maintain that don't bring value

[alice-i-cecile]

Yeah, I think I agree with @mockersf here on reflection. The "standalone" crates for Bevy are:

• bevy_ecs
• bevy_reflect
• bevy_math
• bevy_color

Those can have an MSRV listed, but the others should not.

Updating it for bevy_mikktspace seems fine though: we definitely shouldn't report incroorect information.

[Brezak]

I've removed the msrv specification from everything but

• bevy
• bevy_color
• bevy_ecs
• bevy_math
• bevy_mikktspace
• bevy_reflect
  I kept bevy_mikktspace because we specify the MSRV in the README.md.

[mockersf]

If this is not checked in CI, it will just become unsynced and useless.

We already check the MSRV for the Bevy crate, it should be added for the others.

I'm still not convinced this bring enough value to be worth the CI time though

[BD103]

rust-version is inheritable. You can add rust-version.workspace = true to all crates, then just update the root Cargo.toml. This wouldn't need testing in CI because we already specify it for bevy.

The only crate that would need to differ from this is probably bevy_mikktspace, which is not really going to be updated and may be useful in the ecosystem.

We're kind checking the per package msrv already. In (1.77.0-1.78.0) clippy gained a lint that checks function msrv. Only thing that isn't happening is we're not checking for msrv incompatible language constructs.
