Support finding Sbom::Occurrences via dependency names

What does this MR do and why?

This MR:

1. Adds Query.components to find Sbom::Components by their name
2. Changes Sbom::DependenciesFinder to support looking up by component_ids

For performance reasons (see !153596 (comment 1927321689) and https://gitlab.slack.com/archives/CNZ8E900G/p1722605163019149) we:

1. First have the user select names of the dependencies for which they want to see the vulnerabilities
2. Find them using Sbom::DependenciesFinder using component_id only so we don't perform a join
