Expose floating arithmetics in RzNum/`rz-ax` tool #3035

Currently, we have RzFloat bitvector API that will be used in RzIL. It would be nice to have it exposed also in the Rizin's calculator - rz-ax, and some of the RzNum APIs.

librz/util/float/*
librz/include/rz_util/rz_float.h

Expose both bitv and float API, and assign new options for them would be nice. For example

-z : convert number as bitvector representation, -Zu/-Zi bitvector -> unsigned/signed integer, -Zf bitvector as signed -> float, -Zp bitvector as unsigned -> float
-zf: caculate float using bitvector arithmetic, and -zi caculate number using bitvector arithmetic

Also 0b literals should be treated as bitvectors by default, to solve this problem: https://github.com/rizinorg/rizin/issues/3331
