<i18n dev> RFR: 8369184: SimpleTimeZone equals() Returns True for Unequal Instances with Different hashCode Values

[Naoto Sato]

Fixing the equals/hashCode contract in the SimpleTimeZone class. The current implementation includes DST rule fields in hash code computation even for zones that do not observe DST, while equals() always considers them. Also correcting the example code in the class description, where it used 20-year-old obsolete "America/Los_Angeles" rule.
