Andreas Kling 49c488c3eb LibWeb: Make CSS::is_inherited_property(PropertyID) go fast ...

Instead of switching on the PropertyID and doing a boatload of
comparisons, we reorder the PropertyID enum so that all inherited
properties are in two contiguous ranges (one for shorthands,
one for longhands).

This replaces the switch statement with two simple range checks.

Note that the property order change is observable via
window.getComputedStyle(), but the order of those properties is
implementation defined anyway.

(cherry picked from commit 1f5c49f40d0383ef1f91d6e4d838230f04dfb738;
amended for stroke-linecap in getComputedStyle-print-all.txt)
