Fix `extra_unused_lifetimes` false positive
This PR fixes#9014.
I confirmed the FP on the `crates.io` source as `@JohnTitor` mentioned, and confirmed that the FP is no longer present following this change.
I did not include a test in this PR because I think constructing one would be complicated, and the fix is pretty simple. But please let me know if this is unacceptable.

Check for `--force-warn` in Clippy's driver run condition
Just a thing I've noticed while tinkering on the driver. Currently, the driver only checks for `--cap-lints=allow` to determine if Clippy should run on the code, but ignores possible `--force-warn` arguments

changelog: Others: Allowing all lints and only `--force-warn`ing some will now work with Clippy's driver
add vec.capacity() to [`slow_vec_initialization`] detection
fix#8800
for example
```rust
let mut vec1 = Vec::with_capacity(len);
vec1.resize(vec1.capacity(), 0);
let mut vec2 = Vec::with_capacity(len);
vec2.extend(repeat(0).take(vec2.capacity()));
```
will trigger the lint

close: #8836
take over: #8853
This PR adds check `todo!` and `unimplemented!` in if_same_then_else.

Thank you in advance.
