Additional testing on the metadata cache

[hiltontj]

Following #25543 and, more specifically, #25552 which only contained a couple of tests, this issue is for testing out a few more scenarios with pushing, querying, and pruning the metadata cache.

Tasks

Beta Give feedback

1. A test case for catching the case where multiple predicates are specified on a single column in the cache feat: metadata cache provider and datafusion trait impls #25566
2. Rows that do not contain all columns in the cache are ignored

[hiltontj]

It is not clear if the test case listed for "Rows that do not contain all columns in the cache are ignored" will be needed once #25585 is completed, since writes missing tags would be invalidated anyway.

If the cache is holding a string field, however, then it may still be relevant. Either way, I don't want to add a test that will break and block the linked issue.
