Maybe is good to create an issue and link this PR

Do you mean I should create an issue in num_cpus? I don't see why this PR would warrant creating an issue.

Why is this function public? Could it simply be moved into the body of HardwareConcurrency(&self)? Since the code is not repeated, I'm not sure an extra function buys us much unless I'm misunderstanding.

It's also called in components/script/dom/workernavigator.rs - I split it out to another function to avoid duplicating the logic in the Navigator and WorkerNavigator.

Implements
navigator.hardwareConcurrency, which returns the number of logical processors available.I used the
num_cpuslibrary (which is already used by Servo in other places), and cache the result since it can be slow to query that information on some operating systems../mach build -ddoes not report any errors./mach test-tidydoes not report any errors
