std: Add a `backtrace` module
This commit adds a `backtrace` module to the standard library, as designed in [RFC 2504]. The `Backtrace` type is intentionally very conservative, effectively only allowing capturing it and printing it. Additionally this commit also adds a `backtrace` method to the `Error` trait which defaults to returning `None`, as specified in [RFC 2504]. More information about the design here can be found in [RFC 2504] and in the [tracking issue]. Implementation-wise this is all based on the `backtrace` crate and very closely mirrors the `backtrace::Backtrace` type on crates.io. Otherwise it's pretty standard in how it handles everything internally. [RFC 2504]: https://github.com/rust-lang/rfcs/blob/master/text/2504-fix-error.md [tracking issue]: https://github.com/rust-lang/rust/issues/53487 cc #53487
