Add constant array support for __builtin_dump_sturct. For N-dimensional arrays, the new dumpArray function dumps the elements of the array by generating N layers of 'for' loops.
for example:
The struct:

  struct Foo {
    int x;
  };
  
  struct S {
    int a[3];
    int b[2][2];
    struct Foo c[2];
  };

The dump result:

  struct S {
      int[3] a = [
          [0] = 1
          [1] = 2
          [2] = 3
      ]
      int[2][2] b = [
          [0] = [
              [0] = 1
              [1] = 2
          ]
          [1] = [
              [0] = 3
              [1] = 4
          ]
      ]
      struct Foo[2] c = [
          [0] = {
              int x = 1
          }
          [1] = {
              int x = 2
          }
      ]
  }
