  [webkitpy] Increase the default number of child processes spawned for arm64 Macs

Reviewed by Jonathan Bedard and Geoffrey Garen.

arm64 Mac hardware can handle more WebKitTestRunner processes than the
default number we calculate. Local testing suggests that doubling the count
yields an 18 minute speedup in overall test runtime on M1 hardware, so lets
hardcode this increase until we implement a more sophisticated test scheduling
mechanism.
