Ting-Yu Lin 26a6db6fb1 Bug 1909761 Part 2 - Create a helper struct IntrinsicSizeInput to aggregate needed data when computing intrinsic inline size. r=dholbert
This patch changes the signature to `GetMinISize()`, `GetPrefISize()`,
`IntrinsicISize` by adding a helper struct as a preparation. Then we can just
add more data such as a percentage basis to the struct without altering the
signature in the future.

When passing `IntrinsicSizeInput` struct down to another helper method, we
generally just pass the original one if the method is computing the intrinsic
size of our own or our anonymous children. If the method is computing our
children's intrinsic contribution, we'll need to create a brand new
`IntrinsicSizeInput` for our children.
