Add SPI to clear web process cache
​https://bugs.webkit.org/show_bug.cgi?id=204210

Patch by Benjamin Nham <Ben Nham> on 2019-11-15
Reviewed by Chris Dumez.

This adds an SPI to clear cached web processes. The intended use case is to add a lukewarm mode to
Mac PLT5 in which web pages load in a new WebProcess and load resources from the disk cache.
