[CSS Grid Layout] Updating -webkit-grid-rows or -webkit-grid-columns doesn't work as expected
​https://bugs.webkit.org/show_bug.cgi?id=107062

Reviewed by Tony Chang.

Source/WebCore:

Tests: fast/css-grid-layout/percent-grid-item-in-percent-grid-track-update.html

fast/css-grid-layout/percent-padding-margin-resolution-grid-item-update.html

This change makes -webkit-grid-rows and -webkit-grid-columns dynamic change properly
relayout their children, thus making them work!

• rendering/RenderGrid.cpp:

(WebCore::RenderGrid::layoutGridItems):
Fixed the logic to force a grid item relayout if the grid area size changes. This is the
safest approach as margins or paddings can also be a percent of the grid area's size.

• rendering/style/RenderStyle.cpp:

(WebCore::RenderStyle::diff):
Fixed a dumb mistake.
