[SPARK-24834] use java comparison for float and double
The methods in `Utils`, `nanSafeCompareDoubles` and `nanSafeCompareFloats`
had
the same semantics as java's `java.lang.Double.compare` and
`java.lang.Float.compare`
respectively.
## What changes were proposed in this pull request?
Remove the two functions in `Utils`, and replace the call sites (only two
for each function) with the corresponding java comparison function.
## How was this patch tested?
Existing spark tests should cover this.
