Description

Describe the feature/enhancement you need

Create an option that allows the developer to enable a mica background for the WebView2 control at WinUI3.

I've saw that there are ways to do it at #3439, but they are kind of complex. But now that in the Flexible System Backdrop Placement feature is live on Windows App SDK experimental 2 release, maybe it can be achieved easily

The scenario/use case where you would use this feature

Enabling transparence on the visited webpages would show the mica backdrop, achieving more integration with Windows and feeling more native.

How important is this request to you?

Nice to have. There are other ways to tackle this, but having official API support would be beneficial.

Research direction

Start by reviewing the existing approach discussed in issue #3439 and the linked Flexible System Backdrop Placement documentation for WinUI3. Determine how a WebView2 control could expose an option for a Mica background and transparent visited webpages; done means the option is available through official API support and produces the requested native backdrop effect.
