ARROW-15661: [Gandiva][C++] Add SHA512 function (#12404)

This PR was created to implement SHA512 functions in Gandiva side. 

This PR implements the follow signatures:

FunctionSignature{name =hashSHA512, return type =String, param types =[int8]}
FunctionSignature{name =hashSHA512, return type =String, param types =[int16]}
FunctionSignature{name =hashSHA512, return type =String, param types =[int32]}
FunctionSignature{name =hashSHA512, return type =String, param types =[int64]}

FunctionSignature{name =hashSHA512, return type =String, param types =[uint8]}
FunctionSignature{name =hashSHA512, return type =String, param types =[uint16]}
FunctionSignature{name =hashSHA512, return type =String, param types =[uint32]}
FunctionSignature{name =hashSHA512, return type =String, param types =[uint64]}

FunctionSignature{name =hashSHA512, return type =String, param types =[float]}
FunctionSignature{name =hashSHA512, return type =String, param types =[double]}

FunctionSignature{name =hashSHA512, return type =String, param types =[boolean]}

FunctionSignature{name =hashSHA512, return type =String, param types =[date64]}
FunctionSignature{name =hashSHA512, return type =String, param types =[date32]}

FunctionSignature{name =hashSHA512, return type =String, param types =[time32]}
FunctionSignature{name =hashSHA512, return type =String, param types =[timestamp]}

FunctionSignature{name =hashSHA512, return type =String, param types =[string]}
