plugins: Fix build error when GL is enabled while EGL is disabled.

Browse source 
gl_platform_type in gst_vaapi_get_display_type_from_gl_env generate
unused-variable warning and may block build when Werror enabled.
Several functions like gst_vaapi_display_egl_new_with_native_display
have no prototype warning and link error when GL is enabled but EGL
is disabled. Fix all these warning and link error.
