Tests: Improve benchmark precision

Summary:

• Improved microbenchmarking with multiple features.

• inline performance critical code
• Average runtime is specified and used to calculate iterations.
• Console: show median of multiple runs
• plot: show box plot
• filter benchmarks
• specify scaling factor
• ignore src/test and src/bench in command line check script
• number of iterations instead of time
• Replaced runtime in BENCHMARK makro number of iterations.
• Added -? to bench_bitcoin
• Benchmark plotly.js URL, width, height can be customized
• Fixed incorrect precision warning
  • Removed CCheckQueueSpeed benchmark

This benchmark's runtime was rather unpredictive on different machines, not really a useful benchmark.

This is a backport of Core PR11517

Depends on D1842 and D1843

Test Plan:

make
./src/bench/becnch_bitcoin
