Replace value class related reflection calls with Methodhandle

[k163377]

This change will improve throughput, at least with value class wraps Int, Long, String, or (Java)UUID.

However, first-time performance will be degraded.
Also, performance may not be improved for value class that wraps other classes.

Although not shown in the benchmark, greater improvement is expected, especially with respect to serialization using JsonValue or JsonKey.

Benchmarks

Using kogera-benchmark, a simple benchmark on value class wrapping Int was performed.
The raw data is uploaded below.

Throughput(Higher is better)

The results show that both serialization and deserialization have improved.

The trend in scores for deserialization is a bit strange, since the improvement should basically be proportional to the number of properties, but it seems to generally improve throughput by 7% or more.
The trend of the scores for serialization is as expected, improving throughput by at least 10%.

Single shot(Lower is better)

From the results, it can be read that the first-time execution performance is degraded.

Among those verified, the amount of this degradation was about 9% at worst and less than 5% in most cases.
