booth: Streamline the low-level circuit emission
...
For the basic single-bit operations, opt for gate cells (`$_AND_` etc.)
instead of the coarse cells (`$and` etc.). For the emission of cells
move to the conventional module methods (`module->addAndGate`) away
from the local helpers. While at it, touch on the surrounding code.

booth: Move away from explicit `Wire` pointers
...
To represent intermediate signals use the `SigBit`/`SigSpec` classes as
is customary in the Yosys codebase. Do not pass around `Wire` pointers
unless we have special reason to.

Speed up the autoname pass by 3x. ( #3945 )
...
* Speed up the autoname pass by 2x. This is accomplished by only constructing IdString objects for plain strings that have a higher score.
* Defer creating IdStrings even further. This increases the speedup to 3x.

Speed up TopoSort. The main sorting algorithm implementation in TopoSort::sort_worker is 11-12x faster. Overall, the complete sequence of building the graph and sorting is about 2.5-3x faster. The overall impact in e.g. the replace_const_cells optimization pass is a ~25% speedup. End-to-end impact on our synthesis flow is about 3%.

dft_tag: Implement `$overwrite_tag` and `$original_tag`
...
This does not correctly handle an `$overwrite_tag` on a module output,
but since we currently require the user to flatten the design for
cross-module dft, this cannot be observed from within the design, only
by manually inspecting the signals in the design.

This is still missing a mode to rewrite $overwrite_tag and $original_tag
by injecting $set_tag and $get_tag in the right places. It's also
missing bit-precise propagation models for shifts and arithmetic and
requires the design to be flattened.
