Update Webview Android JS builtins added version

[SessionHu]

Summary

This PR updates JavaScript builtins support version of Webview Android. Most changes are changing ≤37 or mirror to ≤4.

Test results and supporting details

I wrote a simple tool to determine if the value is undefined to check if the browser supports this feature (only implemented 3 checks so far). Which is available at SessionHu/check-js-feat.
Then I run the server on my another device and open the page on the old Android 4.2 TV with an browser which using Android System Webview.
Here is the result photo (UserAgent on the top, support features in green background, unsupport in red. And I cannot take screenshot on that device):

here 3 photos shot on phone camera

Although the system version is 4.2.1 instead of 4 according to the navigator.userAgent and System Settings. I believe it has the same behavior as 4. Because I did not find Android Webview 4.2 release in /browsers/webview_android.json.

I also do some other tests on that device. But test code were already removed before this PR opened.

I'm not too excited about the changes away from "mirror". I don't think WebView Android shipped things earlier than Chrome here. So, this might suggest that the chrome versions could be set to earlier in these cases.

Perhaps my test results were influenced by device provider. In fact, Android 4 might not support some ES5 features as well as Chrome. So I reverted some changes based on the relevant information.
