Platform DRM (#1388)
* updated README.md * fixed CMakeLists.txt to allow building and debugging with Visual Studio Code and CMAKE Tools extension * added PLATFORM_DRM contains mouse pointer code from https://github.com/chriscamacho * removed redundant cleanup in InitGraphicsDevice * fixed DRM connector mode selection * added choosen DRM connected mode to log output * added respecting TargetFPS on DRM mode selection, default to 60 * added support for GetMonitorRefreshRate * changed SUPPORT_MOUSE_CURSOR_RPI to SUPPORT_MOUSE_CURSOR_NATIVE * changed avoidProgressive to allowInterlaced * cleanup, function extraction and improved mode selection * README reverted to original for PR * line endings fixed for core.c * removed old code * mouse pointer reverted to small square * replaced SetGraphicDeviceName() by DEFAULT_GRAPHIC_DEVICE_DRM Co-authored-by: kernelkinetic <kernelkinetic@outlook.com>
