Ensure bulk saves also trigger the password saved listeners (#6526)

Task/Issue URL:
https://app.asana.com/1/137249556945/project/488551667048375/task/1210974473587922?focus=true

### Description
- We have a `PasswordStoreEventListener` plugin which allows other code
to be notified when a password has been saved
- This is called for individual password saves, but bulk insertions
doesn't trigger it

### Steps to test this PR

Suggested logcat filter: `m_autofill_onboardeduser`

### Required testing

#### Importing passwords from Google Passwords
- [ ] Fresh install on a device with a modern `WebView` (e.g.., not an
old emulator)
- [ ] Visit Password management screen (`Overflow -> Passwords`) and
choose to `Import Passwords From Google`
- [ ] Go through the flow until success
- [ ] Verify `m_autofill_onboardeduser` is in the logs

### Optional extra testing (functionality unchanged)

#### Manually adding a credential
- [ ] Fresh install, visit Password management screen and manually add a
password
- [ ] Verify `m_autofill_onboardeduser` is in the logs. 

#### Saving a credential from website autofill
- [ ] Fresh install, visit https://fill.dev/form/login-simple, add
username and password (>= 4 characters) and login
- [ ] Save when prompted
- [ ] Verify `m_autofill_onboardeduser` is in the logs. 

#### Manually adding a credential
- [ ] Fresh install, visit Password management screen and manually add a
password
- [ ] Verify `m_autofill_onboardeduser` is in the logs.
