fix(log): inconsistent webview log target

[Legend-Master]

Make webview log target more consistent that it always starts with "webview"

The WEBVIEW_TARGET target (the value used to be "Webview") is never actually being used before, and the location info was only generated for the webkit based before (also they seem to be the current location instead of the caller's location)

So this PR changes the behavior to use the caller's location, format it like webview:bar@filename.js:6:3, fallback to webview

Fix #1058
