Add bevy_error! and bail! macros to BevyError

[loreball]

Objective

These macros were originally part of #23684 but were removed to help the pr cross the finish line.

Solution

Reintroduce and discuss them here.

Testing

2 testcases to prove the expanded code compiles.

---

bevy_ecs has been expanded with 2 macros to simplify creation of BevyErrors.

// Now instead of this.
let error = BevyError::new(Severity::Panic, "hello error");
// You can do this. It even support `format!` syntax
let error = bevy_error!("{} bottles of beer on the wall.", 99);

// Quickly return from a fallible system using bail.
bail!("{} bottles of beer.", 99);
// Expands to something like this
return Err(BevyError::panic("Take on down, pass it around,");

// You can even specify the severity by passing it in as the first argument
bevy_error!(Severity::Debug, "{} bottles of beer on the wall.", 98);

I have no idea how this code could change the rendering. I'm guessing it's a false alarm since image upload failed. It's that or a miscompilation.
