I started using `CreateMockVulkanContext()` in #45654, and discovered that it was not thread-safe. This PR does a little bit of refactoring/TLC to ensure that functions and buffers can be accessed across threads (like the _real_ `ContextVK`). The attached test (_test for a test fixture, hoorah!_) fails consistently before the changes, and passes after. Note that if you try testing this with `--gtest_repeat=10000` (at least that's the threshold for me), it'll fail - that's actually due to flutter/flutter#134482 which in turn is being fixed in #45686.

Fixes flutter/flutter#134482.
I wish I knew how to create the thread in
::Create(), but given the constructor is private I feel less bad about reverting part of #45474. Added a test that consistently fails before this PR and passes after.(Unblocks flutter/flutter#133198)
