Docs: Update for properties
Add properties page, move cell_gate and cell_word under a singular cell_index along with properties.  Fix links accordingly.

Also drop x-aware and x-output todos since they are resolved.

Cell properties
---------------
.. TODO:: Fill :cell:ref:`is_evaluable`
.. cell:defprop:: is_evaluable
.. cell:defprop:: x-aware
Some passes will treat these cells as the non 'x' aware cell. For example,
during synthesis `$eqx` will typically be treated as `$eq`.
.. cell:defprop:: x-output
These cells can produce 'x' output even if all inputs are defined. For
example, a `$div` cell with ``B=0`` has undefined output.
Refer to the :ref:`propindex` for the list of cells with a given property.
