Add increment/decrement

## Summary

Ignoring all lines until the first logical line does not match the
behavior from pycodestyle. This PR therefore removes the `if
state.is_not_first_logical_line` skipping the line check before the
first logical line, and applies it only to `E302`.

For example, in the snippet below a rule violation should be detected on
the second comment and on the import.

```python
# first comment




# second comment




import foo
```

Fixes #10374

## Test Plan

Add test cases, update the snapshots and verify the ecosystem check output
