7994: Speed up mbe matching in heavy recursive cases r=edwin0cheng a=edwin0cheng

In some cases (e.g.  #4186), mbe matching is very slow due to a lot of copy and allocation for bindings, this PR try to solve this problem by introduce a semi "link-list" approach for bindings building.

I used this [test case](https://github.com/weiznich/minimal_example_for_rust_81262) (for `features(32-column-tables)`) to run following command to benchmark:
```
time rust-analyzer analysis-stats  --load-output-dirs ./ 
```

Before this PR : 2 mins
After this PR: 3 seconds.

However, for 64-column-tables cases, we still need 4 mins to complete. 

I will try to investigate in the following weeks.
