fix: Correctly parse the minimum value of int64 (#41009) 
issue: #40729 

Current approach to parse negative numbers is first parse the numeric
part and then multiply the result by -1(mainly to distinguish the
precedence of the negative sign and the subtraction operator). However,
for the minimum value of int64(`-9223372036854775808`), the value
`9223372036854775808` already exceeds the representable range of int64.
As a result, parsing error occurs.
Therefore, use a specific rule to match `-9223372036854775808`.
