Jannis Harder 5524d5185d tcl: Return scratchpad result.json and result.string as tcl objects 
This makes it possible for yosys commands to return values when invoked
as tcl commands. Right now no commands natively support this, but the
tee command can be used with json output like this:

```tcl
set stat [yosys tee -q -s result.json stat -json -top top]
dict get $stat modules \\top num_cells_by_type \$pmux
```

Or with newline separated lists like this:

```tcl
split [yosys tee -q -s result.string select -list top] "\n"
```

cells enable compact encoding and decoding of 3-valued logic signals
using multiple 2-valued signals.

Jannis Harder 605d127517 simlib: Silence iverilog warning for `$lut` 
iverilog complains about implicitly truncating LUT when connecting it to
the `$bmux` A input. This explicitly truncates it to avoid that warning
without changing the behaviour otherwise.

This updates satgen and simlib to use a `$pmux` model where the output
