Clicking `Generate Password` after `Cancel` should generate a new password

[adamsilverstein]

This issue was brought to my attention by @TheLastCicada.

On screens with the new password generation feature, we offer users a button to Cancel the generate password action (see #33079). If the user clicks Cancel (say for example they don't like the generated password), then decides the click Generate Password again, the field shows the same password as before.

A nice enhancement here would be to regenerate the password each time the user clicked Cancel and then clicked Generate Password again.

Proposed fix, adds ajax callback to regenerate password, fires when user clicks Cancel, in preparation for next 'Generate Password

• Refresh against trunk.

I verified that the ajax callback is only available to logged in users - hitting the endpoint after logout in a different tab gave me a '0' result. This makes sense because the callback action is added to $core_actions_post which results in ajax endpoints without the nopriv_ variation required for privileged users to access.

• The summary for wp_ajax_generate_password() should be something like "AJAX handler for generating a password"
• Since wp-utils is already a dependency of user-profile we can use wp.ajax() here.

Changing milestone because this is an enhancement.

Thanks for the feedback, I will refresh the patch.

Profile: when clicking "Cancel" after clicking "Generate Password", request and generate a new password to present to the user.
