The index of each RT is the remapped color attachment index, so we have
to use the remapped indices when telling the HW the number of RTs.
This fixes KHR-GLES3.framebuffer_blit.scissor_blit on ANGLE once we
enabled VK_EXT_multisampled_render_to_single_sampled, which switched
ANGLE to using dynamic rendering with
VK_KHR_dynamic_rendering_local_read.
Fixes: d50eef5b06 ("tu: Support color attachment remapping")
