[PR] [api] Avoid overflow in VectorType default size [paimon]

QuakeWang opened a new pull request, #8360:
URL: https://github.com/apache/paimon/pull/8360

   ### Purpose
   
   `VectorType.defaultSize()` previously multiplied the element default size by the vector length using int arithmetic. For very large vector lengths, this could overflow and return a negative size estimate.
   
   This PR uses `MathUtils.multiplySafely` to cap overflow at `Integer.MAX_VALUE` and keep size estimation valid.
   
   ### Tests
   
     - `mvn -pl paimon-api -Pfast-build -Dtest=VectorTypeTest test`
     - `mvn -pl paimon-api -Pfast-build -DskipTests compile`
     - `mvn -pl paimon-api -Dtest=VectorTypeTest test`
