fix minor alignment warning
...
this is a prototype definition error:
`_mm_storeu_si128()` should accept a `void*` pointer,
since it explicitly states that it accepts unaligned addresses
yet requiring a `__m128i*` tells otherwise, and requires the compiler the enforce this alignment.

fix one minor alignment warning
...
seems like a prototype interface error:
input parameter should have been `const void*`,
since the documentation is explicit that input doesn't have to be aligned,
but `const __m256i*` makes the compiler enforce it.

minor: generalize BitContainerType
...
technically equivalent to `size_t`,
but it's the proper type for underlying register representation.
This makes it possible to control register type, and therefore size, independently from `size_t`,
which can be useful on systems where `size_t` is 32-bit, while the architecture supports 64-bit registers.

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
