This bug is to enable tab unloading on macOS. Bug 1587762 enabled tab unloading for Windows. On Mac, with bug 1714382 we started listening for OS memory pressure events on macOS and including the memory pressure state in crash reports and event pings (bug 1723604).
This bug is filed to cover enabling tab unloading and the memory-pressure Gecko notification on low memory.

Enable tab unloading on macOS when the OS memory pressure level reaches "critical".
Add a gtest that exercises the memory pressure response by testing that a tab unload attempt occurs and the internal memory-pressure notification is sent. Test does not cause a real OS memory pressure event.
Use the memory_pressure(1) macOS command to generate artificial memory pressure events to test the browser response. For example, the following artificially puts the OS in the "critical" memory pressure level for 60 seconds.
$ sudo memory_pressure -S -l critical -s 60

This enhancement was part of the work done on QA-1196 "Tab Unloading in Nightly 95" bugwork.
Considering the above, I'm marking this enhancement as Verified.
