KSES: Allow SVG presentation attributes in safe_style_css.

Add SVG presentation attributes to the list of CSS properties allowed by `safecss_filter_attr()`, so inline SVG markup can be styled via the `style` attribute.

This ports Gutenberg PR #79172 to Core.

Props afercia, westonruter, wildworks.
Fixes #65457.
