Collect compat data for each type for attr()

[stof]

BCD has compat data for <type-or-unit> for attr which is supported by the collector, but it also has additional subfeatures for the support of each type: https://developer.mozilla.org/en-US/docs/Web/CSS/attr#browser_compatibility

The fact that the collector does not support them leads to an inconsistent state where the collector-based update for the Chrome 133 release marked <type-or-unit> as supported but kept all types as unsupported.
It would be great to collect all subfeatures of attr
