[vulkan] Implement most of the parser

Browse source 
This gets renderpass parsing almost working (not hooked up, though). The
missing bits are support for expressions for flags (namely support for
the | operator) and references (eg $swapchain.format). However, this
shows that the basic concept for the parser is working.
