Unrolled build for #148301

Rollup merge of #148301 - GuillaumeGomez:import-filter, r=notriddle

[rustdoc search] Include extern crates when filtering on `import`

As discussed #147909, some filters should have been "grouped". This PR allows extern crates to match the `import` filter.

This PR also allowed me to uncover a bug for the URL generated for renamed extern crates. Opened #148300 for it.
