Measure reading bindings in the performance suite

The suite covered reading bindings only through `getBindings` with two
variables, so `matchBindings` — the entry point a query engine actually uses —
was never measured, and neither was a bindings pattern that produces few
results per lookup.

Reading bindings gets its own `bindings` scope, holding the existing
two-variable sweep, the same sweep read through the `matchBindings` async
iterator, and a one-variable sweep that spreads the same number of results over
many more lookups, which is what a join produces.

It is a scope of its own rather than extra cases inside `triples` because
CodSpeed measures each scope as a single benchmark: adding cases to `triples`
changes what that benchmark measures and is reported as a regression on every
`| triples` benchmark, even though the code did not get slower. The scope runs
at half the dimension, like `quoted` already does, which keeps the cost of a
full benchmark run in line with what it was before.
