Auto-instrument user interactions as transactions

[AbhiPrasad]

Problem Statement

This helps address issues like #3169, and fix issues like #4072.

It would be a great feature if we could auto-instrument user interactions as transactions. This needs to work similarily to what we did for Android and iOS already.

The main interaction to capture is probably clicks, we can explore more after that!

In addition, this will help with stuff like supporting INP - as we can more carefully track user interactions as a performance metric.

Solution Brainstorm

On click, create a ui.action transaction. This can be tagged with information about the click event.

This will need to be opt-in, as it could potentially spike user's quota.
