These tests expect the window's client area size to be (kWSize, kWSize). Use
::AdjustWindowRect to offset TestWindowDelegate's preferred size so that the
client area size is correct after the OS internally applies frame insets during
::CreateWindow.
To test: Run `ceftests.exe --gtest_filter=ViewsWindowTest.Window*`.
All tests should pass.
