CLDR-17461 Forum posts in vetting view, boost performance, change icons

-Add a cache localeForumStatusMap in SurveyForum.java

-New class SurveyForum.LocaleForumStatus

-Get all the status for a locale with a single sql call

-Clear the cache for a locale when a post is added/closed

-Revise icons in the Comparison (English) column: 👁️‍🗨️ and 💬

-👁️‍🗨️ means: This item has one or more forum posts, some of which are open

-💬 means: This item has one or more forum posts, all of which are closed

-Change let to const for two items in cldrSurvey.mjs; remove @Property

-Call expediteStatusUpdate in cldrForum to update the table when a post is added/closed

-Call updateRowEnglishComparisonCell even if isSetup, and always removeAllChildNodes; old optimization assumed the cell contents never changed
