This commit adds support for SystemVerilog array-to-array assignment
operations that were previously unsupported:
1. Direct array assignment: `b = a;`
2. Array ternary expressions: `out = sel ? a : b;`
Both single-dimensional and multi-dimensional unpacked arrays are
supported. The implementation expands these array operations during
AST simplification into element-wise assignments.
Example of now-supported syntax:
```systemverilog
wire [7:0] state_regs[8];
wire [7:0] r[8];
wire [7:0] sel[8];
assign sel = condition ? state_regs : r;
```
