Correctly encode item visibility in metadata
This fixes private statics and functions from being usable cross-crates, along with some bad privacy error messages. This is a reopening of #8365 with all the privacy checks in privacy.rs instead of resolve.rs (where they should be anyway). These maps of exported items will hopefully get used for generating documentation by rustdoc Closes #8592
