[feature request] update to new version of webview

[congzhangzh]

Hi devs,

as the bundle of webview is very old, is that possible you update the submodule to the latest?

Tks,
Cong

There has been some pretty major build changes since last updated. I would love to update it, but I simply do not have the time for what would be a pretty major overhaul. I can ofc review and help according to my ability and energy but don't expect (actually, never expect anything of anyone in the open-source space) that I will do it any time soon. The best way to get it done would be to do it yourself!
