Increase disk cache capacity when there is lots of free space
https://bugs.webkit.org/show_bug.cgi?id=158526
Reviewed by Chris Dumez.
Our maximum disk cache capacity has been 175MB for a very long time. Meanwhile the average resource size has grown
massively. 175MB is now enough for cacheable resources of a few dozen sites at most. Using bigger caches when there is
room for it can reduce network traffic, reduce disk writes, save battery and speed up page loading.
This patch changes cache size for PrimaryWebBrowser cache model
>=16GB free: 175MB -> 500MB
8-16GB free: 150MB -> 250MB
and modestly for DocumentBrowser
>=16GB free: 50MB -> 75MB
Note that if system (on Cocoa platforms) really needs disk space it will wipe out caches so this doesn't reduce
available disk space in scenarios like software installation.
