BUG: import_optional_dependency doesn't check version for submodules
xref https://github.com/pandas-dev/pandas/pull/38370#discussion_r550723991

We'd like `import_optional_dependency` to correctly handle submodule imports AND to be able to import a specified minimum version of the dependency (for when a particular feature requires higher than global minimum version).

```
In [14]: import pandas as pd
    ...: from pandas.compat._optional import import_optional_dependency
    ...: import_optional_dependency("pyarrow.csv", min_version="3.0")
