Auto merge of #16335 - lnicola:salsa-lz4-file-text, r=Veykril

Browse source 
internal: Compress file text using LZ4

I haven't tested properly, but this roughly looks like:

```
1246 MB
    59mb   4899 FileTextQuery

1008 MB
    20mb   4899 CompressedFileTextQuery
   555kb   1790 FileTextQuery
```

We might want to test on something more interesting, like `bevy`.
