Add support for selective cookie filtering in MV3

### Issue Details

Currently there is no way to use modifyHeaders selectively in MV3. That means we don't have a way to use rules such as
`||*/httpbin/cookies^$cookie=case5` where we have a specific cookie name for example.

### Proposed solution

- We can use filter for modifyHeaders to filter out only specific cookies.
