Map "@import" to web-features (#57000)

classifies form-validity-pseudos web feature (#56822)

Map gradients web-feature (#56663)

Feature: gradients
Reference: https://github.com/web-platform-dx/web-features/blob/main/features/gradients.yml

Notable exclusions

1. css/css-images/gradient/ - The majority of files in this directory test gradient-interpolation (e.g., in srgb, hue interpolation) or conic-gradients. These files were excluded to avoid mapping them to the baseline gradients feature. They should be mapped to their respective features in a future update.

Notable inclusions

1. css/css-images/radial-gradient-container-relative-units-*.html - Included as they verify gradients accept container-relative units (core syntax).

2. compat/webkit-*-gradient*.html - Included as they test compatibility aliases which map to standard gradients.
