New Lint: disallowed_method
Fixes https://github.com/rust-lang/rust-clippy/issues/6073
I added a `disallowed_method` lint that works similar to `blacklisted_name`, e.g allows config-defined disallowed method calls.
This lint allows advanced users to patch in undesired method calls for specific projects. It basically uses the DefId of method calls and matches it to parsed strings. Is there an alternative approach that could use more easily digestible configuration strings?
All tests pass as expected except for a linting error on `ui/redundant_pattern_matching_option`, which I am not sure how to resolve since I don't think I changed anything affecting it.
changelog: Add disallowed_method lint to warn on user-defined method calls
Fix FP in `print_stdout`
Fix#6041
This lint shouldn't be emitted in `build.rs` as `println!` and `print!` are used for the build script.

UI tests cleanup
`@matthiaskrgr` noticed some `run-pass` annotations in some crash tests that were added in #3922. At that moment they seemed to be necessary to make the tests fail in case of an ICE, but they do not seem to be needed anymore. To test this I forced an ICE in a file with and without annotations, with and without stderr files, and the ICE makes the test fail every time.
In addition, I've applied a suggestion from `@ehuss` and `@jyn514` to add `emit=metadata` to the rustc flags for the UI tests. In my machine this improved the run time from ~17 to ~12 seconds.

Allow a unique name to be assigned to dataflow graphviz output
Previously, if the same analysis were invoked multiple times in a single compilation session, the graphviz output for later runs would overwrite that of previous runs. Allow callers to add a unique identifier to each run so this can be avoided.
