Subject: [PATCH] [libc++][test][NFC] Remove unused inclusions of `<iostream>`
 (#134776)

Some test files for flat container adaptors redundantly include
`<iostream>` and, surprisingly, `<cstddef>`. This patch removes the
redundant inclusions.

Inclusions of `<vector>` is also removed since a sane implementation is
expected to make instantiation of `flat_(multi)map<K, V>` or
`flat_(multi)set<K>` valid when only `<flat_map>` or `<flat_set>` is
included.
