Auto merge of #115296 - saethlin:dont-duplicate-allocs, r=jackh726
Load include_bytes! directly into an Lrc This PR deletes an innocent-looking `.into()` that was converting from a `Vec<u8>` to `Lrc<[u8]>`. This has significant runtime and memory overhead when using `include_bytes!` to pull in a large binary file.
