This PR updates all of our x/y named utilities (like `px-*`, `my-*`,
`inset-y-*`, `scroll-px-*`, etc.) to use logical properties like
`padding-inline` instead of separate `padding-left` and `padding-right`
properties.
We held off on this originally for a while because `inline` doesn't
really mean _horizontal_ like the "x" in `px-*` implies, but I think in
practice this change is fine — I'm comfortable with "x" meaning "in the
inline direction" and "y" meaning "in the block direction" in Tailwind.
This is technically a breaking change if anyone was depending on the
fact that `px-*` for instance was always explicitly setting
`padding-left` and `padding-right` even when building something in a
vertical writing mode, but I kinda doubt there's a single real project
on the internet that will actually be affected, so not too worried about
it.
If someone _really_ wants to set `padding-left` and `padding-right` they
can always use `pl-4 pr-4` instead of `px-4`.
Nice thing about this change is it produces quite a bit less CSS.
To test this change, I re-generated all of the snapshots and made sure
none of the generated utilities changed position or anything in the
output (initially they did before I updated `property-order.ts` to add
some missing properties).
I also created a little demo locally in the Vite playground to test
things manually and make sure I didn't make any obvious typos or
anything that could slip through the snapshots:

I didn't manually test the scroll padding or scroll margin utilities
because they are more annoying to set up, but I probably should.
