Bug 2003897 - Add telemetry for credit card editor actions r=android-reviewers,fmasalha

This patch introduces Glean telemetry for user interactions within the credit card editor.

Metrics are now recorded for the following actions:
- `CreditCards.saved`: When a new credit card is successfully saved.
- `CreditCards.modified`: When an existing credit card is updated.
- `CreditCards.deleted`: When a credit card is deleted.
