Fix implementation of VK_EXT_texel_buffer_alignment.

Correct maximum number of texel buffer elements for the native texture
buffer case. With an 8-bit format, I assume it's possible to create a
texture buffer spanning the entire 3.5 GiB (the maximum size of a buffer
on my GPU).

Set the structure type in the physical device's
`_texelBuffAlignProperties` struct. Otherwise, when it gets written out
to a chain, the structure type will be lost, and it wouldn't e.g. show
up in `vulkaninfo`.

Fix enumeration of formats when one of the members of the
`VkFormatProperties` is zero. I intended that to mean "don't care," but
it was erroneously filtering out, well, everything. Now we actually
accurately report the minimum alignment requirements.
