Backends: support for multiple imgui context with little testing (#586, #1851, #2004, #3012, #3934, #4141)

Browse Source 
I believe more renderer backends should work. GLFW/Win32/SDL/Vulkan probably have many issues.

- Demo: Fixed requirement in 1.83 to link with imgui_demo.cpp if IMGUI_DISABLE_METRICS_WINDOW is not set. (#4171)
Normally the right way to disable compiling the demo is to set IMGUI_DISABLE_DEMO_WINDOWS, but we want to avoid
implying that the file is required.
- Backends: Reorganized most backends (Win32, SDL, GLFW, OpenGL2/3, DX9/10/11/12, Vulkan, Allegro) to pull data
from a single structure to facilitate usage with multiple-contexts. (#586, #1851, #2004, #3012, #3934, #4141)
- Backends: Reorganized most backends (Win32, SDL, GLFW, OpenGL2/3, DX9/10/11/12, Vulkan, Allegro) to pull their
data from a single structure stored inside the main Dear ImGui context. This facilitate/allow usage of standard
backends with multiple-contexts BUT is only partially tested and not well supported. It is generally advised to
instead use the multi-viewports feature of docking branch where a single Dear ImGui context can be used accross
multiple windows. (#586, #1851, #2004, #3012, #3934, #4141)
- Backends: Win32: Rework to handle certains Windows 8.1/10 features without a manifest. (#4200, #4191)
- ImGui_ImplWin32_GetDpiScaleForMonitor() will handle per-monitor DPI on Windows 10 without a manifest.
- ImGui_ImplWin32_EnableDpiAwareness() will call SetProcessDpiAwareness() fallback on Windows 8.1 without a manifest.
