Vulkan: Fix infinite loop in state_rebuilder.

The problematic case is a state containing multiple pipelines, some of which
have 0 basePipeline, and some of which have a basePipeline that forms a loop or
doesn't exist. This caused both `numHandled` and `len(unhandledPipelines)` to be
non-zero forever. This change resets `numHandled` for each pass over
`unhandledPipelines`.

Fixes #2390
