Auto merge of #107753 - kylematsuda:type-of, r=BoxyUwU

Switch to `EarlyBinder` for `type_of` query

Part of the work to finish #105779 and implement https://github.com/rust-lang/types-team/issues/78.

Several queries `X` have a `bound_X` variant that wraps the output in `EarlyBinder`. This adds `EarlyBinder` to the return type of the `type_of` query and removes `bound_type_of`.
