bors 11bbb52313 Auto merge of #83214 - cjgillot:dep-map, r=michaelwoerister 
Mmap the incremental data instead of reading it.

Instead of reading the full incremental state using `fs::read_file`, we memmap it using a private read-only file-backed map.
This allows the system to reclaim any memory we are not using, while ensuring we are not polluted by
outside modifications to the file.
