18dca11dd0 Backends: GLFW, SDL2: ImplXXX_GetContentScaleXXX() helpers return 1.0f on emscripten / apple / android (#8742, #8733) 
We can divide platforms into two cases based on how they report screen geometry:
- Case 1: Platforms which report screen size in "physical pixels": Windows (for "Dpi aware" apps), Linux (with Wayland)
- Case 2: Platforms which report screen size in "density-independent pixels": macOS, iOS, Android, emscripten

As a consequence, there are two important things we need to know:
- FramebufferScale: The scaling factor FrameBufferSize / ScreenSize
  - In case 1, the framebuffer size is equal to the screen size and DisplayFramebufferScale=1.
  - In case 2, the framebuffer size is equal to the screen size multiplied by a factor, for example DisplayFramebufferScale=2.
- ContentScale The scaling factor for the content that we will display
  - In case 1, the content scale will often need to be > 1 (e.g., 2), because we will need to display bigger elements so that they show with a correct physical size on the screen.
  - In case 2, the content scale is equal to 1
This commit fixes ContentScale for platforms in case 2.
