Update google benchmark to v1.9.1 (#222)

* Update google benchmark to v1.9.1

Updated MicroBenchmarks/lib/benchmark/ using update_benchmark.sh with the
change below:

```

* Fix MicroBenchmark build on Linux with clang 18.1.8 (#141)

MicroBenchmarks/libs/benchmark/test/options_test.cc fails to build
on Linux/AArch64 with following error:
error: variable 'actual_iterations' set but not used

This patch adds benchmark::DoNotOptimize(actual_iterations); to
to function BM_explicit_iteration_count in options_test.cc

-Wall and -Werror were being used to compile and I am surprised that
this was not caught by any of the buildbots.
Some versions of clang compile this all fine with -Wall -Werror.
