Openjdk-tests: Investigate license requirements for several MBCS data files

[smlambert]

AIX_ko_KR.IBM-eucKR.txt
AIX_KO_KR.UTF-8.txt
Linux_ko_KR.UTF-8.txt
BreakIteratorTest.out
win_ko.txt

Contain the following license/copyright statement:

IMdkit를 제외한 부분은
황치덕에게 저작권이
있으며 이의 사용은
GPL에 따라야합니다. COPYING
파일 참조

which translates as:

All parts except IMdkit are copyrighted by Hwang Chi-deok, and its use is
It must be in accordance with the GPL. COPYING file reference

Question:
can we remove and/or replace these files with more permissive licenses (GPL is not permissive enough) in order to transition them as part of this repository to the Eclipse foundation (under the Adoptium github organization).

FYI @KKES335 @takiguc - your input is requested.

@smlambert
Thank you for your notification.
These are data files for BreakIterator testcase on Korean locale.
I'll check them with my co-workers and get back to you.

@smlambert
We created new Korean data files against i18n.
Also we found regex testcase had same kind of issue.
So we created new Korean data files against regex.

Thank you for your quick response @takiguc ! We will intend to merge #2534 once we unfreeze this repo after our release activities are complete.
