[Fix](planner) fix ScalarType.getAssignmentCompatibleType() when deal
boolean and decimal (#34435)
The legacy planner encounters issues when handling filters such as:
c1(boolean type)=0.0(decimalv3).
The literal 0.0 is interpreted as decimalv3(1,1), and the boolean type c1
is coerced to decimalv3(1,1).
decimalv3(1,1) can only retain values in the range [0,1), while the boolean
true is represented as 1, exceeding the upper bound, thus causing an overflow
problem.
This pull request addresses this issue by considering the boolean type as
decimalv3(1,0), making both c1 and 0.0 being cast to decimal(2,1).
