Add benchmarks for the json v2 package

[kevinburkesegment]

Go 1.25 ships with encoding/json/v2 behind a GOEXPERIMENT flag. It would be useful to see how this new package compares in terms of performance.

[kevinburkesegment]

Running 20 benchmarks with each of json/json-v2 on my Mac, here are the results I got. Could be a noisy computer but a noisy computer wouldn't affect the alloc results

goos: darwin
goarch: arm64
