Don't register properties with types unless necessary (#15215)

This PR updates many of our `@property` rules to use `syntax: "*"`
instead of a specific type.

Registering custom properties with types triggers all sorts of obscure
edge-case bugs in different browsers (mostly Safari, sometimes Firefox),
but using `"*"` always seems to work. So unless we know we actually need
to animate a custom property, it's safer to register is as `"*"`.

Many of the places our custom properties are used are already inherently
animatable (like the `translate`, `scale`, and `transform`) even when
the underlying properties are not typed, so removing types for things
like `--tw-scale-x` doesn't actually stop the `scale-*` utilities from
being animateable.

I've also updated the `--tw-gradient-from/via/to-position` properties to
use `<length-percentage>` instead of `<length> | <percentage>` because
for some reason I don't understand, only `<length-percentage>` works
correctly when using `calc(…)` in arbitrary values.

Fixes #15188,
#14277.
