Special-case suggestions for null pointers constness cast
This implements the suggestions from #13361. It fits into the existing `ptr_cast_constness` lint, as this is a specialized version. However,
1. I have not modified the lint MSRV, so the documentation for this lint will still show that it applies only from Rust 1.72.0. This is true in the general case, but the lint for null pointers will trigger even before this version as `null()` and `null_mut()` were already present in Rust 1.0 and there is no reason not to apply this lint. I guess this is only a minor documentation issue that can be ignored.
2. I have not covered the `core::ptr::null::<T>().cast_mut()` (could be made into `core::ptr::null_mut::<T>()`) and `cotr::ptr::null_mut::<T>().cast_const()` (could be made into `core::ptr::null::<T>()`) cases. Should they be covered? If they should, here or in a separate PR?

Fix#13361
Bump ui_test
This should give a bunch of ui improvements when lots of tests are running. Please lmk of any issues with it. Switching to `--quiet` should always avoid any issues, so there's a workaround if anything crops up. Also please check that this does not regress performance for you. It doesn't for me, but that doesn't mean much.

Visit struct fields recursively in uninit fallback check
This makes the fallback a bit more consistent with the other checks and rustc.
Fixes#13364. When using a generic type as the `Vec` element type like the issue title says, rustc's uninit check fails and our fallback is used, which didn't look at struct fields when it could.

Fix possible typo in `ptr_arg` lint
This fixes a possible typo in the [`ptr_arg`](https://rust-lang.github.io/rust-clippy/master/index.html#/ptr_arg) lint. I'm new to Rust, so apologies if I misunderstood the meaning of this lint.

move `manual_c_str_literals` to complexity
IMO the suggestion to use `c""` literals over a hardcoded `\0` byte string literal has some fairly strong upsides (no need to manually null-terminate it and the compiler checks for intermediary null bytes) that this should just be enabled by default.
It's also written slightly conservatively to only emit a warning when we can be reasonably confident that the lint is *actually* applicable (that is, lint on e.g. `b"foo\0".as_ptr()` but not `b"foo\0"`. The latter looks like a c-string but its type is `&[u8; _]`, and if it's used in a context where a byte slice is needed then you have no nice way to convert to it from a `c"foo"` literal of type `&CStr`).
