Bug 1717204 - Increase the number of threads used by the XPCOM thread pool to match the number of cores r=bas

Browse Source 
Currently the XPCOM thead pool creates one less thread than the number of
cores. The JS helper thread pool creates an equal number.

I tested increasing the number of threads to match the number of cores and
found it resolved this regression.
