Fixed a bug where Houdini crashed on shutdown if a USD Preview Surface shader was cooked in the session.

Work items in PDG nodes that support caching will now always effect the cache state of downstream work items. For example, if a work item in a node with the cache mode parameter set to Automatic ends up writing a new file to disk, all downstream work items that also use caching will have their results invalidated. Those work items will also need to recook unless they have their cache setting set to Read Files.

There is also a new HOUDINI_PDG_CACHE_DEBUG environment variable that can be set to a value between 0 and 3 in order to get debug output about why PDG is or is not loading a file from cache. A value of 0 means the output is disabled, and a value of 3 is the most detailed output.

Fix a recently introduced bug in the Edit Context Options LOP where not all context options would be put into the "options block". Also fixed an issue where the hou.contextOption method would not cause a Python LOP to recook when the default value for the requested context option was changed.
