Subject: [PATCH] Adds support for tests and benchmarks via Vcpkg features

Enables building unit tests using GTest and benchmarks using Benchmark,
through Vcpkg features.

Adds `tests` and `benchmark` features to `vcpkg.json`,
and adds corresponding CMake logic to control their build based on
Vcpkg manifest features.
