  [JSC] Use Identifier::from in IdentifierArena::makeNumericIdentifier

Reviewed by Keith Miller.

We should just use Identifier::from from IdentifierArena::makeNumericIdentifier, which can have some optimization additionally via per-VM string cache.
Also, we can use `canBeInt32` to check wether we can stringify it as int32_t instead of double, which is much faster.
