backends/native: Add fake cursor plane using impl_device's crtcs

Browse Source 
Because `meta_kms_impl_device_simple_initable_init` is called in the
middle of `meta_kms_device_new`, the crtcs list for `MetaKmsDevice`
has not been populated yet. And thus the loop to detect missing
cursor planes and create fake ones never iterated. But the crtcs list
does already exist in `MetaKmsImplDevice` so iterate over that instead.

Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/3264
