nir/print: Print access qualifiers for intrinsics

nir/print: Print access qualifiers for intrinsics

Instead of printing an opaque integer that needs to be manually decoded.
Example output:

    32x4   %7 = @image_load (%4 (0x0), %6, %5 (0x0), %4 (0x0)) (image_dim=2D, image_array=false, format=r8g8b8a8_snorm, access=readonly|reorderable, range_base=0, dest_type=float32)
