Describe the feature

Found from nitrojs/nitro#2174

Drivers such as fs/fsLite currently modify options objects. this might have unwanted side-effects especially if input options are used in different places.

We should:

• Make defineDriver types to make sure options object is (deep) ReadOnly
• Possibly update tests to make sure there is no runtime update
• Fix drivers that currently modify input to instead, make a copy of object
