Allow custom multiplier in Benchmark::ThreadRange (#2304)

Currently Benchmark::ThreadRange hardcodes a geometric multiplier of 2 when generating thread counts across [min_threads, max_threads]. In contrast, DenseThreadRange allows a configurable stride parameter.

Add an optional mult parameter to Benchmark::ThreadRange (defaulting to 2) so users can specify geometric multipliers other than 2 (e.g. powers of 4 or 8) across thread ranges.

- Update ThreadRange in benchmark_api.h and benchmark_register.cc.

- Add unit tests in test/benchmark_test.cc and test/options_test.cc.

- Document the mult parameter and DenseThreadRange in docs/user_guide.md.

Closes #1531.
