RFR: 8376406: Avoid loading ArrayDeque in jdk.internal.loader.NativeLibraries

[Eirik Bjørsnøs]

Please review this PR which replaces `ArrayDeque` with `ArrayList` for the native library context stack in `jdk.internal.loader.NativeLibraries.NativeLibraryContext`.

With this follow-up to similar changes in #29288 and #29430, a simple JAR-based "hello world" program no longer loads the `ArrayDeque` class during startup.

The change here is mostly a straightforward replacement. The existing processing was a FIFO stack, which it still is after this PR, just backed by ArrayList instead.

Since ArrayList is null-friendly, I added an explicit `Objects.requireNullNull` before pushing to the stack.

Pure refactoring, no tests updated, `noreg-cleanup`.
