[SPARK-31439][SQL] Fix perf regression of fromJavaDate

Browse source 
### What changes were proposed in this pull request?
In the PR, I propose to re-use optimized implementation of days rebase function `rebaseJulianToGregorianDays()` introduced by the PR #28067 in conversion of `java.sql.Date` values to Catalyst's `DATE` values. The function `fromJavaDate` in `DateTimeUtils` was re-written by taking the implementation from Spark 2.4, and by rebasing the final results via `rebaseJulianToGregorianDays()`.

Also I updated `DateTimeBenchmark`, and added a benchmark for conversion from `java.sql.Date`.

### Why are the changes needed?
The PR fixes the regression of parallelizing a collection of `java.sql.Date` values, and improves performance of converting external values to Catalyst's `DATE` values:
- x4 on the master branch
- 30% against Spark 2.4.6-SNAPSHOT

Spark 2.4.6-SNAPSHOT:
```
To/from java.sql.Timestamp:               Best Time(ms)   Avg Time(ms)   Stdev(ms)    Rate(M/s)   Per Row(ns)   Relative
------------------------------------------------------------------------------------------------------------------------
From java.sql.Date                                  614            655          43          8.1         122.8       1.0X
```

Before the changes:
```
To/from java.sql.Timestamp:               Best Time(ms)   Avg Time(ms)   Stdev(ms)    Rate(M/s)   Per Row(ns)   Relative
------------------------------------------------------------------------------------------------------------------------
From java.sql.Date                                 1154           1206          46          4.3         230.9       1.0X
```

After:
```
To/from java.sql.Timestamp:               Best Time(ms)   Avg Time(ms)   Stdev(ms)    Rate(M/s)   Per Row(ns)   Relative
------------------------------------------------------------------------------------------------------------------------
From java.sql.Date                                  427            434           7         11.7          85.3       1.0X
```

### Does this PR introduce any user-facing change?
No

### How was this patch tested?
- By existing tests suites, in particular, `DateTimeUtilsSuite`, `RebaseDateTimeSuite`, `DateFunctionsSuite`, `DateExpressionsSuite`.
- Re-run `DateTimeBenchmark` in the environment:
