Remove web3 shim usage event (#20376)

Browse Source 
Removes the `Website Accessed window.web3 Shim` event from the `metamask_logWeb3ShimUsage` RPC method implementation. The method itself displays an alert to the user if a website attempts to access the `window.web3` shim, which we replaced the original, functional `window.web3` object with after said object was removed. This seems potentially useful, because we still get 5-star reviews on [the legacy web3 extension](https://addons.mozilla.org/en-US/firefox/addon/metamask-legacy-web3/).

The associated metrics event, on the other hand, is useless. It is rife with false positives, and doesn't tell us anything that we can't learn from download data for the legacy web3 extension. It's time to get rid of it.
