[clang-format] Handle Verilog delay control (#95703)

I made a mistake when I tried to make the code handle the backtick
character like the hash character.  The code did not recognize the delay
control structure.  It caused net names in the declaration to be aligned
to the type name instead of the first net name.

new

```Verilog
wire logic #0 mynet, //
              mynet1;
```

old

```Verilog
wire logic #0 mynet, //
     mynet1;
```
