[ozone/wayland] Convert WaylandCursorPosition to operate in DIP

... instead of pixels.

It happens today that WaylandCursorPosition stores the last mouse
position in pixels, instead of DIP.

In lacros, this position is queried by the call to
`display::Screen::GetScreen()->GetCursorScreenPoint()` in
`ImmersiveFullscreenController::UpdateLocatedEventRevealedLock()`,
for instance by hovering the mouse cursor over the upper display
boundary in immersive fullscreen mode, so that the tabstrip slides
down.
When a high DPI display is used, the mismatch occurs.

This CL changes WaylandCursorPosition to store the last mouse cursor
position in DIP, instead of pixels.

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.

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.
