BMI2 detection in 32-bit mode

no longer limit automated BMI2 detection to x64
...
this was previously no triggered in x86 32-bit mode,
due to a limitation in `bitstream.h`, that was fixed in #4248 .
Now, `bmi2` will be automatically detected and triggered
at compilation time, if the corresponding instruction set is enabled,
even in 32-bit mode.
Also: updated library documentation, to feature STATIC_BMI2 build variable

do not solve the equation, even though some members cancel each other,
this is done for clarity,
we'll let the compiler do the resolution at compile time.
