RFR: 8324233: Update JPEG Image Decoding Software to 9f

[Jayathirth D V]

IJG has released latest version of libjpeg 9f and we need to update our version also match 9f changes.
IJG reference : https://www.ijg.org/

With updated changes both headless and headful tests are green on all platforms.

Also while updating to 9f noticed that many files don't have latest copyright year and comments from previous version updates like 9e, so updated that part also to match 9f version.
