Parse attributes before annotations

Problem/Motivation

In 📌 Use PHP attributes instead of doctrine annotations Fixed we switched to parsing annotations before attributes. This is not great for performance when core is converted.

At some point in the future, potentially around the time 11.0.0 is released, most contrib will also be converted, and then it'll be even worse for performance.

Opening to see if we can switch the order back again, for example in 10.4.0 or 10.5.0
