render/egl: initialize wlr_egl with EGL_PLATFORM_DEVICE_EXT

Browse source 
Uses the EXT_device_query extension to get the EGL device matching the
requested DRM file descriptor. If the extension is not supported or no device
is found, the EGL device will be retrieved using GBM.

Depends on the EGL_EXT_device_enumeration to get the list of EGL devices.
