Correctly configure transparent TrayBubbleView

Background: A transparent TrayBubbleView is used as a container for
hosting content.

Reasons for the change: To ensure a transparent tray bubble after the
changes in crrev.com/c/6501740, the bubble background color must be
explicitly set to transparent. This is because that change will cause
the client view to always be painted to a layer. Currently, this is not
a problem as TrayBubbleView does not paint its client view to a layer,
so a background on the client view is not painted. Setting the
background to transparent is a prerequisite for crrev.com/c/6501740 to
avoid painting a default background.

Also a transparent bubble should not apply rounded corners, since the
contents of a transparent TrayBubbleView handles its own rounded
corners.

Refactor: Instead of using TrayBubbleView::InitParams to specify the
radius BubbleBorder, we now use the BubbleDialogDelegate to configure
the bubble rounded corners.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
