Add UnhandledError telemetry error report

How to Test

Use latest code and open workspace in preview env https://hw-vserror-report.preview.gitpod-dev.com/workspaces

Browser Error Catch

• Toggle browser DevTool Console, exec code below

async function willThrow(str) {
    throw new Error(str);
}
willThrow('<anything_you_want>')

• Go to GCP error report search with what you has throwed. It should be here with service named vscode-web. Access log detail,userId workspaceId instanceId should exists
• GCP error report should have only one message that you just sent, without service vscode-server since we filter them

Server Error Catch

TODO...

Need to add debug commit for it, but we can manually get an error by changing browser resources code, to make fromBrowser always false to make browser telemetry duplicate in server

Global search with "@gitpod/ide-metrics-api-grpcweb": "ak-ext-metrics" and found it. Why we need this dependency in the remote and remote/web folders?

to distribute them for web (remote/web) and backend (remote) during the build, in the root only dev time deps

This error stack is omitted, since vscode thought it's private data

openvscode-server/src/vs/platform/telemetry/common/telemetryService.ts

{ label: 'Email', regex: /@[a-zA-Z0-9-.]+/ } // Regex which matches @*.site

I skimmed through the code, it looks like it would do what we want. Clean up history and bring it in?
