[JSC] Put some destructible objects to IsoSubspace
https://bugs.webkit.org/show_bug.cgi?id=204771

Reviewed by Mark Lam.

This patch puts DateInstance, ErrorInstance, and Intl objects in IsoSubspace.
By using specific IsoHeapCellType, we can use JSNonFinalObject as base-classes of
them instead of using JSDestructibleObject. We also introduce STATIC_ASSERT_ISO_SUBSPACE_SHARABLE
to ensure that derived class of some IsoSubspace'ed one is intentional and safe.
