Array and single type overrides now allow the parsing of the items
themselves to be customized. This makes it easy to handle arrays and
pointers to single items while also using custom specifications, rather
than relying entirely on the custom override.
It worked as a proof of concept, but as the code itself needs to be a
bit smarter, it would be a lot smarter to break up that code to make it
easier to work on the individual parts.
The tables are generated from the enums pulled out of the vulkan headers
using a ruamoko program (thanks to its reflection capabilities). They
will be used for parsing property lists used to create render passes and
pipelines.
