[neon/backports-noble/wayland-noble/Neon/release] protocol: Add missing wl_shm_pool::error enum

[Jonas Ådahl]

Git commit 79e3150782b7067f4ae345305e6a4eac5930be95 by Jonas Ådahl, on behalf of Robert Ancell.

Add missing wl_shm_pool::error enum

Existing implementations are using wl_shm::error for errors that apply to both
wl_shm and wl_shm_pool. The existing error values are assigned to the new
enum so existing code will continue to work but it will now be clearer what
errors can be emitted. wl_shm::error::invalid_format is now unused.
