-----------
Add CSS syntax for position-context
https://bugs.webkit.org/show_bug.cgi?id=324213
rdar://187409104
Reviewed by Tim Nguyen.
Add `position-context: container | anchor` from the Spatial CSS spec draft,
parsing and computed value only — nothing reads it yet.
Gated on ENABLE_SPATIAL_PORTAL and the SpatialPortalEnabled setting, so nothing
changes on other platforms or with the feature off.
