tools: ynl-gen: track attribute use
For range validation we'll need to know if any individual attribute is used on input (i.e. whether we will generate a policy for it). Track this information. Link: https://lore.kernel.org/r/20231018163917.2514503-2-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
