render/pixel-format: Move has_alpha into it's own array

Browse source 
Some opaque pixel formats (nv12, p010) require per-plane bytes_per_block
info. However, it doesn't make sense to store them in
wlr_pixel_format_info, as they will never be useful (currently, this
info is used for shm, which doesn't have a concept of multi-planar
buffers.)

Let's define a separate array and function for determining whether a
pixel format has alpha.
