Reduce size of j.t.f.DateTimePrintContext::adjust

[wenshao]

By adding the JVM startup parameters `-XX:+UnlockDiagnosticVMOptions -XX:+PrintInlining` and analyzing the printed log information, and found that the code size of the j.t.f.DateTimePrintContext::adjust method is 382, which is greater than 325, causing inlining failure.
Below is the log message:
```
@ 7 java.time.format.DateTimePrintContext::adjust (382 bytes) failed to inline: hot method too big
```
We can extract the exception-generating code into two smaller methods, reducing the code size from 382 to 322, allowing C2 to inline the DateTimePrintContext::adjust method.
The refactored code looks like this:
```java
 private static TemporalAccessor adjust(final TemporalAccessor temporal, DateTimeFormatter formatter) {
 // ...
 if (overrideZone.normalized() instanceof ZoneOffset && temporal.isSupported(OFFSET_SECONDS) &&
 temporal.get(OFFSET_SECONDS) != overrideZone.getRules().getOffset(Instant.EPOCH).getTotalSeconds()) {
 throw unableApplyOverrideZone(temporal, overrideZone);
 }
 // ....
 if (f.isDateBased() && temporal.isSupported(f)) {
 throw unableApplyOverrideChronology(temporal, overrideChrono);
 // ...
 }
 private static DateTimeException unableApplyOverrideChronology(TemporalAccessor temporal, Chronology overrideChrono) {
 return new DateTimeException("Unable to apply override chronology '" + overrideChrono +
 "' because the temporal object being formatted contains date fields but" +
 " does not represent a whole date: " + temporal);
 }
 private static DateTimeException unableApplyOverrideZone(TemporalAccessor temporal, ZoneId overrideZone) {
 return new DateTimeException("Unable to apply override zone '" + overrideZone +
 "' because the temporal object being formatted has a different offset but" +
 " does not represent an instant: " + temporal);
 }
```
I submitted a draft Pull Request https://github.com/openjdk/jdk/pull/26633 <https://github.com/openjdk/jdk/pull/26633 > , Hope to get your feedback.
