dev: Handle too-small `k` error in `CircuitLayout::render`
...
In most places within `CircuitLayout`, we are flexible on `k`. However,
for tracking selectors we need to know the number of rows. We could
change this, but given that we also want the number of rows to be
accurate for rendering unusable rows, we can instead use this as an
opportunity to inform the user that they will need to bump `k`.

Add trait methods and general APIs for defining circuit constants
...
During circuit configuration, fixed columns can be marked as suitable
for containing arbitrary constant values (i.e. the columns aren't
encumbered by constraints that preclude arbitrary values).
During synthesis, circuits can now request that the layouter assign
an advice cell within a region, to some specified constant value. It
is the layouter's responsibility to find space within the previously
marked fixed columns, in which to assign the constant.
This commit intentionally does not compile.

Introduce a FloorPlanner trait and integrate it into the Circuit trait
...
This is the beginning of the process to enable full floor planning
capabilities in `halo2`. For now, all that a floor planner can do is
synthesize a circuit, which makes it no more powerful than a layouter,
but easier to use (as moving to a multi-pass layouter no longer requires
changes to `Circuit::synthesize`).
