After change to release page heap lock around returning memory back to
kernel, page heap test got dependency on page heap lock. Which was not
available on windows since relevant symbols are not exported.
Proposed fix is to simply duplicate all needed .cc files in
page_heap_test project instead of linking to dll. This is not perfect
but gets job done, until we figure out better solution (GNU/Linux will
eventually get hidden visibility and will need it).
This fixes github issue 1189.
