Add a rule to enforce lazy imports (#23777)
## Summary
`TID254` enforces the use of `lazy` imports. You can specify a set of
modules, similar to `banned-module-level-imports`, or `"all"`:
```toml
# Require every module-level import to be lazy.
banned-eager-imports = "all"
# Require lazy imports for specific modules.
banned-eager-imports = [
"boto3",
"botocore",
]
```
