Nishan 1a49892d57 fix: linear gradient color stop fix up spec (#45969) ...

Summary:
- Color stops needs to follow [fix up spec](https://drafts.csswg.org/css-images-4/#color-stop-fixup)
- Adds multiple stops syntax support. e.g. linear-gradient(red 30% 50%, green).
- Rename `position` to `positions` in object style API. Optional string array here makes more sense. We'll add number array support once `px` support is added. Will do it as a follow up to this PR.

TODOs: transition hint syntax support `linear-gradient(red, 50%, green)` (Done locally, dependent on this PR). `px` support.

## Changelog:
[GENERAL] [FIXED] - Linear gradient color stop spec.
