work: account for task_group_base interface change in oneTBB 2022.0.0

mattyjams commented 3 weeks ago

The m_wait_ctx member being used in a narrow band of oneTBB versions was removed in a refactor that went into version v2022.0.0 which was released yesterday: https://github.com/oneapi-src/oneTBB/commit/1f52f5093ec7ce23829fe64ab82ac5541fea42ee

This change accounts for the update in the new version of oneTBB and uses the newly added m_wait_vertex member to access the same context as before.

I am far from an expert in the TBB API or the intricacies of this area of libwork, but wanted to offer this up as it allowed me to successfully build OpenUSD against the latest version of oneTBB. I have not done any performance profiling with the new oneTBB version.
