JDK-8190484 was created as a follow-up bug to the unification of the
duplicated jvm.h, jvm_md.h and jmm.h, to determine the proper location
of these files. This has now been decided to be hotspot/share/include
and hotspot/os/$OS/include, respectively.
This patch moves the relevant files there, but since this also frees up
the src/$MODULE/native/include directories for the original purpose, it
also unifies and simplifies the build logic for these directories, so
that common code is executed for all modules to just copy any exported
header files from these directories, should they exist.
I'm intending to push this to jdk-hs.
