Remove ImportMap (#11234)

Browse source 
## Summary

This PR removes the `ImportMap` implementation and all its routing
through ruff.

The import map was added in https://github.com/astral-sh/ruff/pull/3243
but we then never ended up using it to do cross file analysis.

We are now working on adding multifile analysis to ruff, and revisit
import resolution as part of it.


```
hyperfine --warmup 10 --runs 20 --setup "./target/release/ruff clean" \
              "./target/release/ruff check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I" \
              "./target/release/ruff-import check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I" 
Benchmark 1: ./target/release/ruff check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I
  Time (mean ± σ):      37.6 ms ±   0.9 ms    [User: 52.2 ms, System: 63.7 ms]
  Range (min … max):    35.8 ms …  39.8 ms    20 runs
 
Benchmark 2: ./target/release/ruff-import check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I
  Time (mean ± σ):      36.0 ms ±   0.7 ms    [User: 50.3 ms, System: 58.4 ms]
  Range (min … max):    34.5 ms …  37.6 ms    20 runs
 
Summary
  ./target/release/ruff-import check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I ran
    1.04 ± 0.03 times faster than ./target/release/ruff check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I
```

I suspect that the performance improvement should even be more
significant for users that otherwise don't have any diagnostics.
