[rustdoc] Remove object methods coming from trait impls in search results?

[GuillaumeGomez]

Currently, if an object A implements a trait B, the search will show both A::whatever and B::whatever. I think this might be a bit too much. Removing this would in addition makes the search-index file ligher.

What do you think @rust-lang/rustdoc ?

[kinnison]

Is there ever a case where traits are the primary interface to a type? In that context it probably makes sense to include A::whatever in the index.

[GuillaumeGomez]

I think it makes sense most of the time. I'm just exploring new leads to reduce search-index.js size. At some time, we might convert it to wasm. To be tested as well.

[kinnison]

Could we load the search index in the background instead?
