Fixes #58700 Fixes #58696 Fixes #49553 Fixes #52210 This commit removes the special rustdoc handling for proc macros, as we can now retrieve their span and attributes just like any other item. A new command-line option is added to rustdoc: `--crate-type`. This takes the same options as rustc's `--crate-type` option. However, all values other than `proc-macro` are treated the same. This allows Rustdoc to enable 'proc macro mode' when handling a proc macro crate. In compiletest, a new 'rustdoc-flags' option is added. This allows us to pass in the '--proc-macro-crate' flag in the absence of Cargo. I've opened [an additional PR to Cargo](https://github.com/rust-lang/cargo/pull/7159) to support passing in this flag. These two PRS can be merged in any order - the Cargo changes will not take effect until the 'cargo' submodule is updated in this repository.
