Auto merge of #12743 - CBSpeir:remove-paths-vec_resize, r=y21

Remove `dead_code` paths

The following paths are `dead_code` and can be removed:

### `clippy_utils::paths::VEC_RESIZE`
* Introduced when `vec_resize_to_zero` lint added in PR rust-lang/rust-clippy#5637
* No longer used after commit rust-lang/rust-clippy@8acc4d2
### `clippy_utils::paths::SLICE_GET`
* Introduced when `get_first` lint added in PR rust-lang/rust-clippy#8882
* No longer used after commit rust-lang/rust-clippy@a8d80d5
### `clippy_utils::paths::STR_BYTES`
* Introduced when `bytes_count_to_len` lint added in PR rust-lang/rust-clippy#8711
* No longer used after commit rust-lang/rust-clippy@ba6a459

When the lints were moved into the `Methods` lint pass, they switched from using paths to diagnostic items.  However, the paths were never removed.  This occurred in PR rust-lang/rust-clippy#8957.

This relates to issue rust-lang/rust-clippy#5393
