needless arbitrary self: handle macros
This fixes two cases related to macros:
* If the parameter comes from expansion, do not lint as the user has no possibility of changing it. This is not directly related to the fixed issue, but we should probably do that.
* If *only* the lifetime name comes from expansion, lint, but allow the user decide the name of the lifetime. In the related issue, the lifetime was unnamed and then renamed by `async_trait`, so just removing the name in the suggestion would work, but in the general case a macro can rename a lifetime that was named differently, and we can't reliably know that name anymore.
As a hint for the reviewer, the expanded code for the test can be checked with this command (from the root dir of the repo):
```sh
rustc -L target/debug/test_build_base/needless_arbitrary_self_type_unfixable.stage-id.aux -Zunpretty=expanded tests/ui/needless_arbitrary_self_type_unfixable.rs
```

Add option to pass a custom codegen backend from a driver
This allows the driver to pass information to the codegen backend. For example the headcrab debugger may in the future want to use cg_clif to JIT code to be injected in the debuggee. This would PR make it possible to tell cg_clif which symbol can be found at which address and to tell it to inject the JITed code into the right process.
This PR may also help with https://github.com/rust-lang/miri/pull/1540 by allowing miri to provide a codegen backend that only emits metadata and doesn't perform any codegen.

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.
changelog: none
