### Please describe the bug 🐞
Because for the conversion to TimestampNanoLiteral, LongLiteral use
```
case TIMESTAMP_NANO:
// assume micros and convert to nanos to match the behavior in the timestamp case above
return new TimestampLiteral(value()).to(type);
```
and if the long value representation of the timestamp nano, it causes
```
SYSTEM ERROR: ArithmeticException: long overflow
(java.lang.ArithmeticException) long overflow
java.lang.Math.multiplyExact():1032
org.apache.iceberg.util.DateTimeUtil.microsToNanos():101
org.apache.iceberg.expressions.Literals$TimestampLiteral.to():445
