RFR: 8234821: remove unused functions from libjli

[Baesken, Matthias]

Hello,  I missed the  reference from windows only code to JLI_MemRealloc ,  new webrev :

Best regards, Matthias



Hello, please review  this small change .
It removed  unneeded functions from libjli (shown  by  link-time-gc) .

libjli contains a few functions that are shown as unused when applying link-time-gc .
Those functions fall into 2 categories :
- totally unused/uncalled functions   (can be deleted )
- functions that are always inlined, but still kept separate when linking    (making them static often helps to remove the unneeded duplicate )


 ( Similar approach has been done to libnet , see : 8234629: remove unused functions from libnet )



Thanks, Matthias
