Add improvements to the Module Debugger

Fix: dragging ignores scroll position When the module debugger is scrolled to the right and an aggregated input is resized, the selected value jumps to the left because it does not account for the scroll offset.
Add support for recognizing X and Z values Currently the module debugger assumes that all signals are 0 or 1. Verilog also works with X and Z which led to weird behavior in the debugger when outputs/wires where not driven and registers where not initialized. For this the value types where changed from numbers to strings and a simple upgrade method was added to convert older .dbgmodule files.
Add support for displaying registers and wires The module debugger currently lackes the ability to debug wires and registers. This PR allows registers and wires to be marked as debug and they will be shown below the outputs. Example:
```
module dff(input clk, input d, output o);
(* lc_debug *)
reg r = 0;
always @(posedge clk) r <= d;
assign o = r;
endmodule
```
