[11u] RFR(M): 8233787 backport: Break cycle in vm_version* includes

[Vladimir Kempik]

Hello
this backport is pretty much needed in jdk11u-dev as it’s one of prerequests (soft one tho) for jep-391 to apply more cleanly.
I was doing this backport multiple times (including to zulu11) and know what a PITA it is.
Looking forward for integration of this into 11u.
Regards, Vladimir.

In most cases, it’s only #include statement changes, caused by factoring out abstract_vm_version.{c|h}pp from vm_version.{c|h}pp. The change did not apply cleanly, for the most part because of this split. The other merge conflicts were trivial (include rearrangement and copyright headers).
