  Respond to thermal pressure more aggressively
https://bugs.webkit.org/show_bug.cgi?id=284586
rdar://141402176

Reviewed by Chris Dumez.

Currently WebKit responds to thermal pressure only by increasing the DOMTimer alignment interval.

This patch adds a preference (RespondToThermalPressureAggressively) which causes to WebKit to
respond to thermal pressure by taking additional actions:

 - Reducing the preferred animation frame rate
 - Disabling autoplay videos without a user gesture
 - Disabling HDR
 - Disabling speculative loads in NetworkProcess

These actions should be safe since we throttle these exact behaviors when enabling low power mode.
