LOG: [AArch64] Improve code generation of bool vector reduce operations (#115713)

* Avoid unnecessary truncation of comparison results in vecreduce_xor
* Optimize generated code for vecreduce_and and vecreduce_or by
comparing against 0.0 to check if all/any of the values are set

Alive2 proof of vecreduce_and and vecreduce_or transformation:
