Shenandoah: regions space needs to be aligned by os::vm_allocation_granularity()

Since some days our Windows x64 tests show an assert in ShenandoahHeap::initialize().

Note: the last known non-failing VM was tested for: 8241665: Configuring --with-jvm-features=-compiler2 fails to build on AArch64, so the bug must have gotten in afterwards.

#
# A fatal error has been detected by the Java Runtime Environment:
