Nothing is drawn over the game any more. The OSD message queue, the
ImGui overlay that drew it (with the shader-compile progress window and
the statistics, projection and scissor windows), and the imgui and implot
libraries are removed from the build.
Core::DisplayMessage now writes to the log, and the former OSD calls
go through it. Shader compilation no longer presents frames outside
retro_run while it waits.
Deleted with it: the "OSD enabled" core option, the OSD, FPS, speed,
graph, statistics and internal-resolution display settings, and the
ImGui shaders and texture conversion.
