JDK-8273508 - Support archived heap objects in SerialGC
Description
The vm.cds.archived.java.heap test property (see test/jtreg-ext/requires/VMProps.java) is ambiguous -- after JDK-8270489, there are two distinct capabilities:

HeapShared::can_write() -- G1 only
HeapShared::can_read() --  G1, Epsilon

A few CDS tests are marked with

    @requires vm.cds.archived.java.heap

These tests actually require the VM to be able to write Java objects into the CDS archive. Therefore, for clarify, they should be changed to use

    @requires vm.cds.write.archived.java.heap
Comments
Fix request [17u I backport this to simplify backporting later changes that use this property. No risk, only a test change. Resolves were necessary. All occurances of the property covered. Tests pass. SAP nighltly testing passed.

This fix is required for JDK-8273508 - "Support archived heap objects in SerialGC". Without this fix, tests marked with "@require vm.cds.archived.java.heap" would be executed even if SerialGC is selected, but this will dump CDS archives without archived heap objects, causing the tests to fail.
