1683294 - Update rayon to 1.5

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, task, P3)

Description

[Nicolas Silva [:nical]]

Rayon can have a pretty big (positive or negative) impact on CPU usage and performance. We are currently using 1.3 and the current crates.io version is 1.5. Let's see if 1.5 is an improvement.
