follow-up to internal cl 880971704

b/490160312

This change adds `bigframes.bigquery.rand()` which wraps the BigQuery
`RAND()` function. It includes a warning about non-determinism in the
docstring.

Additionally, `SqlScalarOp` has been updated to accept an
`is_deterministic` argument, which is set to `False` for `rand()`.

Fixes customer request for this function. 🦕

Fixes #<issue_number_goes_here> 🦕

The .describe() method attempts to compute metrics like mean, max, and
unique on all columns. For MM complex types (structs representing
images/videos), running COUNT(DISTINCT column) or mathematical
aggregates is physically prohibited by BigQuery and raises syntax/type
validation errors.

We limit aggregations on OBJ_REF_DTYPE and JSON columns to only a basic
.count(), skipping unhashable/unsupported summary metrics.
