[TASKMGR] Favor _countof(), no functional change intended (#5757) 
Taskmgr used a mixture: Sometimes _countof(), sometimes ARRAYSIZE()
and sometimes it calculated the count plain by sizeof(var)/sizeof(TYPE).
Harmonize everywhere to _countof() as it is the shortest solution.

Fix some formatting sins, like placing comments before else-statement.
Shorten the length of some very long line
intentionally *without introducing additional linebreaks* !

Shorten vertical length of some functions to increase their chance to
fit on the screen without scrolling.

Fix wrong indentation level in TaskManagerWndProc().

*.rc: Remove superfluous and redundant comment in all langs

No functional change intended.
