Subject: [PATCH] bench: add benchmarks to `@stdlib/object/any-own-by`

Added missing benchmark/benchmark.js (a benchmark suite is present in
25/26 = 96% of @stdlib/object siblings, and some benchmark directory is
present in 96.5% of non-tooling stdlib packages that ship a lib/main.js
implementation; any-own-by was the sole namespace member with no
benchmark directory). Registered the directory in package.json
`directories` ("benchmark": "./benchmark"; present in 25/25 of the
siblings that ship benchmarks).

The benchmark mirrors the sibling `@stdlib/object/any-in-by`,
exercising the predicate path against built-in and manual-loop
baselines over own enumerable properties. No public behavior,
signatures, or test expectations change.
