RFR: 8311604: Simplify NOCOOPS requested addresses for archived heap objects [v2]

[Ioi Lam]

> This PR attempts to clean up some of the cruds in the existing code:
> 
> - Simplified the calculation of "requested address" when `UseCompressedOops` is disabled -- the archived heap objects are always written starting from 0x10000000
> - Removed `HeapShared::to_requested_address()` so we don't have two kinds of "requested address"
> - Updated the comments about "source" vs "buffered" vs "requested" addresses in archiveHeapWriter.hpp
> - Removed `SerializeClosure::oop()` as the only oop we need to store into the archive header is `HeapShared::roots()`, which can be handled more easily with `FileMapHeader::_heap_roots_offset`
> - Removed some unnecessary dependencies on `G1CollectedHeap::heap()->reserved()`
> 
> Also:
> - Moved SerializeClosure to its own header file to improve build time.
> - Fixed DeterministicDump.java, which wasn't archiving Java objects when  `UseCompressedOops` was disabled.
