WIP: Add a test for maximum number of columns and cell sizes

This adds a parameterized test which creates, inserts into, and scans
some very wide tables (up to 2^12 columns). The columns either have
INT64 or 16KB BINARY columns.

In release/slow mode, they write/read a large amount of data, to ensure
they flush to disk, etc. In debug/fast modes, they write much less.

Because writing extremely wide tables requires a high ulimit, this
automatically avoids instantiating the wider test cases when ulimit
is low. I verified on Jenkins that the limit is high.
