Use JSValue::toWTFString instead of calling toString(exec) and value(exec)

Use JSValue::toWTFString instead of calling toString(exec) and value(exec)

Reviewed by Saam Barati.

Source/JavaScriptCore:

In old days, we frequently use the idiom like, `value.toString(exec)->value(exec)` to
get WTFString from the given JSValue. But now, we have better function, `toWTFString`.
`toWTFString` does not create intermediate JSString objects, then reduce unnecessary
allocations.

This patch mechanically replaces `value.toString(exec)->value(exec)` with `toWTFString(exec)`.
