Firebase Dynamic Links Pass custom parameters to destination

[yonib05]

When using a firebase dynamic link either created through the UI or through the SDK it should persist any unknown parameters to the destination.

For example, if you create a dynamic link:
https://app.link/category -> mywebsite.com/category
When using it you add some custom 3rd party parameters like "token" or "utm-custom" it should persist to the destination.

Example:
https://app.link/category?token=112345 -> mywebsite.com/category?token=112345
https://app.link/category?utm-custom=112345 -> mywebsite.com/category?utm-custom=112345

Currently, you are forced to either create a new dynamic link for each token or use the manual link construction when in reality if we want to use these links on 3rd party platforms such as email they may add some dynamic parameters that we would want to persist that would not.
