Extend finding components to plugins and executables distributed by forc

[alfiedotwtf]

When checking if a component is distributed by forc, we currently only look at forc's direct executables. This needs to be extended to resolve components, plugins, and executables.

This fixes a few issues found while investigating #665.

perhaps we could consider adding 2 more tests here.

#[test]
fn test_resolve_from_name_nonexistent() {
    assert!(Component::resolve_from_name("nonexistent-component").is_none());
}

#[test]
fn test_resolve_from_name_case_sensitivity() {
    let original = Component::resolve_from_name("forc");
    let uppercase = Component::resolve_from_name("FORC");
    assert_ne!(original, uppercase);
}
