arrow: [Benchmarks] All cpp microbenchmarks are failing with new GTest CMake Error

Describe the bug, including details regarding any error messages, version, and platform.

Since the PR https://github.com/apache/arrow/pull/34765 was merged, the cpp-micro benchmarks are failing with the following error:

CMake Error at cmake_modules/ThirdpartyToolchain.cmake:2236 (message):
  System GTest is built with a C++ standard lower than 17.  Use bundled GTest
  via passing in CMake flag

  -DGTest_SOURCE="BUNDLED"

Here is an example Buildkite build.

This error message was explicitly added in that PR, so we’ll need to take action to correct it.
