jdk_foreign excludes

   -java/foreign/TestMatrix.java \
    -java/foreign/TestUpcallStress.java

jdk/open/test/jdk$ jtreg -nativepath:../../../../jdk-24_linux-x64_bin-tests/jdk/jtreg/native/ java/foreign/TestMatrix.java
Test results: passed: 21

extract them to a new group
jdk_foreign_stress which can be added to tier4
