fix(diagnostic): remove invalid buffers from cache (#16397)

Browse Source 
Errors were being caused by invalid buffers being kept around in
diagnostic_cache, so add a metatable to diagnostic_cache which attaches
to new buffers in the cache, removing them after they are invalidated.

Closes #16391.
