GH-34339: [R] Add `skip_rows_after_names` option to `read_csv_arrow`'s options (#34340)

### Rationale for this change

The `skip_rows_after_names` option implemented in C++ was not exposed to R.

### What changes are included in this PR?

The new `skip_rows_after_names` option is now available for the `read_csv_arrow` function.

``` r
> csv <- "a,b\n1,2\n3,4"
> arrow::read_csv_arrow(I(csv), read_options = list(skip_rows_after_names = 1))
# A tibble: 1 × 2
      a     b
  <int> <int>
1     3     4
```

### Are these changes tested?

Tests are added for the new option.

### Are there any user-facing changes?

The new `skip_rows_after_names` option can be used.
* Closes: #34339
