design tokens spec dimension tokens

[tkgroot]

I revisited the design token specification and saw that the spec has changed for dimensions tokens. I was already hacking together some changes for shadow/css/shorthand transformer and maybe more, but before I go and get loose on this, maybe good to know what your take on this is.

do you actually want to implement these spec changes in the first place? since the changes are mostly breaking with existing implementations I was wondering if I should make them backwards-compatible?

"spacing-stack-0": {
    "$value": {
      "value": 0,
      "unit": "px"
    },
    "$type": "dimension"
}

i'm happy and willing to contribute and help implement these wherever necessary. just would like to align first before creating unnecessary work.
