Extending system values

[zslabs]

As part of #1713 when using strickTokens - it mentions catching typos in properties that are defined in your config.

// config.strictTokens = true
css({ display: 'flex' }) // OK, didn't throw
css({ display: 'block' }) // OK, didn't throw
css({ display: 'abc' }) // ✅ will throw since 'abc' is not a valid value for 'display'

What I'm struggling with is how we further extend properties like scale or willChange in the config - as they don't appear to be listed as tokens. If this is possible; is there a spot in the docs I missed (or that should be added)? An example would be adding support for willChange: 'transform'.

SystemProperties.willChange?: ConditionalValue<Globals | "auto" | "contents" | "scroll-position"> | undefined
