Update new PMs shown, select PM, and form shown analytics for vertical mode

Summary

Update new PMs shown, select PM, and form shown analytics for vertical mode

Motivation

Ensure we have the analytic events listed here for vertical mode. This PR doesn't cover all of the info there, but ensures we send mc_carousel_payment_method_tapped, mc_{complete/custom}_sheet_new_pm_show, and mc_form_shown from the correct places.

Testing

• Added tests
• Modified tests
• Manually verified

Manually verified with debugger

[amk-stripe]

renamed this function and the corresponding PaymentSheetEvent, because this analytic event is for mc_{complete/custom}_sheet_newpm_show. It's not actually form-specific, that was just the horizontal mode behavior.
