Rollup merge of #69251 - anp:track-caller-in-traits, r=eddyb

#[track_caller] in traits

Per https://github.com/rust-lang/rust/issues/47809#issuecomment-572791760, this allows the `#[track_caller]` attribute on trait methods.

Includes tests for `#[track_caller]` with:

* "regular" trait impls
* default trait impls
* "blanket-tracked" trait impls, where the annotation is in the trait definition and is inherited by "regular" impls of the trait
Empowering everyone to build reliable and efficient software.
