This PR slightly changes the CMake config such that we can manually assign the architecture we want to compile to, e.g.:

cmake -B build -DSIMPLE_FAST_FLOAT_BENCHMARK_MARCH=x86-64-v4

It also adds the scripts/test_x86_levels.bash file to automatically compile and benchmark the different x86-64 architectural levels (https://en.wikipedia.org/wiki/X86-64#Microarchitecture_levels).
