1602907 - Add thread priority and affinity code for non-Windows

Status: RESOLVED INVALID

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

Description

[Bert Peers [:bpeers]]

Bug 1595708 added a low priority thread pool for improved responsiveness under heavy load, but before activating the feature the thread pools should be configured with proper priority and affinity on each platform.

For Windows this code is done:
https://searchfox.org/mozilla-central/source/gfx/webrender_bindings/src/bindings.rs#1075

For other platforms we need to write the Posix/libc/... code and/or decide which crate is the best option.
