Review contents of JDK25 and JDK26 Problemlists

We can remove all references to 32-bit platforms in these files. We should also verify that the excludes still "make sense", running Grinders to see if the tests still fail, and running our script which checks the state of the issue under which the testcase has been excluded.

https://github.com/adoptium/aqa-tests/blob/master/openjdk/excludes/ProblemList_openjdk25.txt
and ProblemList_openjdk26.txt once it is added via #6746.

Review openjdk/excludes/ProblemList_openjdk25.txt and, once added through #6746, ProblemList_openjdk26.txt. Remove references to 32-bit platforms, run the Grinders to verify whether excluded tests still fail, and run the issue-state checking script. Done means the excludes remain justified and obsolete references are removed.
