Fixes #87548
The issue occurred because we were continuously allocating local references to
jstring
objects inGodotJavaWrapper::has_feature(...)
and not deleting them after using them.In addition to deleting local references in that method, I took a pass at the rest of the codebase and did the same where needed.
Additional testing would be appreciated to ensure no regressions where introduced in the cleanup.
