refactor(allocator): fix mut_from_ref clippy warnings

[overlookmotel]

Continuation of #21210.

Remove #[expect(clippy::mut_from_ref)]attribute from top level, and add it on all methods which take an immutable &self and return a &mut reference. This usually-unsound pattern is sound here as Bump uses interior mutability.

• Added #[expect(clippy::mut_from_ref)] to a set of Bump allocation helpers that return mutable references from &self.
