This is a reland of 92edf9a1

Introduce map handle again to prevent corruption.

Drive-by-fix:
Make some PropertyDetails and Representation methods constexpr.

Original change's description:
> [runtime] Optimise paired instance type checks
>
> Clang doesn't optimise over handle derefs. Change the ValueSerializer
> and the JsonStringifier to use InstanceType directly for checks.
> This CL squeezes another 1.5% of JSON.stringify in local benchmarks.
>
> Drive-by-fix:
> - Avoid a few more derefs in the JsonStringifier
> - Make JsonStringifier::SerializeJSArray a bit more readable
