Stepper Onboarding: Add logic to skip submit step event

[agrullon95]

Fixes: #95125

Proposed Changes

• Adds logic to allow skipping calypso_signup_actions_submit_step event

Why are these changes being made?

• Allows us to skip the event if necessary like in the use-my-domain step. The event should only fire after submitting on final screen for that step.

Testing Instructions

• Checkout branch or use live link
• Navigate to /setup/onboarding.
• Open the Chrome dev tools Network tab and filter by calypso_signup_actions_submit_step
• Click on the Use a domain I own link.
• Enter a domain in the input field and verify that the calypso_signup_actions_submit_step is NOT triggered.
• Click the Transfer your domain and Connect your domain options by clicking Select and verify the calypso_signup_actions_submit_step for both scenarios.

Here is how your PR affects size of JS and CSS bundles shipped to the user's browser:

App Entrypoints (~24 bytes added 📈 [gzipped])

name           parsed_size           gzip_size
entry-stepper        +25 B  (+0.0%)      +24 B  (+0.0%)

Common code that is always downloaded and parsed every time the app is loaded, no matter which route is used.

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.

This event triggers every time you call the submit function, which is why the calypso_signup_actions_submit_step event is triggered multiple times within the use-my-domain component.
