celledges: Use b_width_capped for left shifts
...
`b_width_capped` already exists for preventing arithmetic overflow, limiting the value of `b_width` to 30. This just changes the left shifts to also use it.
The caveat of incorrect results for extremely large values of `a_width` still applies, as does the improbability of that actually happening.
This fixes #4844 (or at least, the floating point exception; the circuit still isn't valid but I think that's fine).

tcl: Update help message to clarify usage of result.string
...
In the current documentation, it's unclear if `result.string` serves as
an example of a string name. It is furthermore unclear what the purpose
of `result.string` is. Clarify this by adding a small explanation (and
fix a typo)

macc: Stop using the B port
...
The B port is for single-bit summands. These can just as well be
represented as an additional summand on the A port (which supports
summands of arbitrary width). An upcoming `$macc_v2` cell won't be
special-casing single-bit summands in any way.
In preparation, make the following changes:
* remove the `bit_ports` field from the `Macc` helper (instead add any
single-bit summands to `ports` next to other summands)
* leave `B` empty on cells emitted from `Macc::to_cell`
