[exo] Apply the correct scaling for cursor bitmap

This patch makes sure that cursor bitmap received via
wl_pointer_set_cursor is scaled correctly before creating the
corresponding PlatformCursor.

The previous approach had two issues:
1. The cursor size was incorrect for scale less than 200% since we used
default DSF (ManagedDisplayInfo::GetDensityRatio()) instead of the
effective one (Display::device_scale_factor()). This led to cursor
always being upscaled to 200%.
2. We didn't use the same logic that ash uses for scaling cursors:
ui::GetScaleForScaleFactor() + ui::GetSupportedScaleFactor(). So the
cursor size was different from ash when using fractional scale.

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.
