Description

Our various code for generating random datasets for testing and benchmarks is a bit verbose / awkward.

I suggest defining a nicer API so we can write code like:

auto arr = random::int32(length, seed);
auto arr = random::varbinary(length, max_value_size, seed);

Since this is only for test code, we can abort if anything returns error Status to make the API more convenient
