[FEA] Establish and run regularly a set of JSON benchmarks

[revans2]

Is your feature request related to a problem? Please describe.

We need a set of JSON benchmarks that we can regularly run to measure if there are any regressions or improvements in JSON performance. We need tests for.

• get_json_object
• json_tuple
• from_json

It would also be nice to have benchmarks for, but they are less common from what we have seen

• the JSON input format
• to_json

Ideally these benchmarks would include long JSON strings with multi-byte characters, and nesting up to 64 deep.

from_json should include a large number of different data types, including arrays, maps, long strings, etc.

get_json_object should include lots of different paths that also include arrays and wildcards.
