render: fix EGL extensions not loaded

Browse source 
Some extensions are only advertised by the EGL implementation with a
non-zero EGLDisplay. That's the case when the extension can only be
enabled when the hardware/driver supports it for instance.

Instead of checking for all extensions without a display, check only for
EGL_EXT_platform_base and EGL_KHR_debug which are used before
eglGetDisplay. Check for all other extensions when we have a display.

Closes: https://github.com/swaywm/wlroots/issues/1955
