Backporting JDK-8346463: Add test coverage for deploying the default provider as a module.

This PR refactors java.nio.file.spi tests to use a module structure and migrates SetDefaultProvider from TestNG to JUnit.

This PR isn't clean due to a conflict in the copyright header in Main.java, and the merge conflict in SetDefaultProvider.java needed to be manually resolved to resemble the Java 25 version because of skipped commits that don't apply to Java 21 (e.g., JEP 468).

For parity with Oracle JDK. Already backported to 25.

Ran related tests on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

make test TEST=test/jdk/java/net/UnixDomainSocketAddress/AddressTest.java
make test TEST=test/jdk/java/nio/file/spi/SetDefaultProvider.java
make test TEST=test/jdk/java/nio/file/spi/TestDelegation.java

Results:

windows-x64-specific-2-test.log
windows-x64-specific-3-test.log
macos-aarch64-specific-test.log
