3990: Switch to Chalk recursive solver r=matklad a=flodiebold

Before:
```
Expressions of unknown type: 5526 (3%)
Expressions of partially unknown type: 5415 (3%)
```
After:
```
Expressions of unknown type: 4600 (2%)
Expressions of partially unknown type: 4645 (2%)
```

On the other hand,
```
'./target/release/rust-analyzer analysis-stats -q . # old solver' ran
    1.24 ± 0.04 times faster than 'rust-analyzer analysis-stats -q . # new solver'
```
I think part of this just comes from the fact that we're inferring more types now; but apart from that, it should be possible to improve the performance a bunch, and I'll make looking into that a priority.
