RFR: 8373561: Replace usages of -verify java launcher option with -Xverify:all JVM option

[Jaikiran Pai]

Can I please get a review of this test-only change which replaces the usages of the deprecated "-verify" java launcher option with "-Xverify:all"?

As noted in https://bugs.openjdk.org/browse/JDK-8373561, the `-verify` `java` launcher option was deprecated for removal in Java 24 and will be removed in some upcoming release. The commit in this PR replaces its usage in tests with the `-Xverify:all` JVM option.

tier1, tier2 and tier3 testing with these changes passed without any related issues. The `test/jdk/javax/swing/JFileChooser/6520101/bug6520101.java` test, that's updated in this PR, was individually run in our CI and that too passed on all headful platforms.
