RFR: 8319873: Add windows implementation for jcmd System.map and System.dump_map [v10]

[Simon Tooke]

> This is a port of [JDK-8318636](https://github.com/openjdk/jdk/pull/16301) to Windows.
> 
> System.map and System.dump_map are implemented using the Windows API and provide roughly the same information in the same format.  Most of the heavy lifting was implemented by @tstuefe in #16301 - this PR adds the Windows implementation and enables the common code for Windows 64 bit.
>  
> [Sample output (with NMT enabled)](https://github.com/user-attachments/files/16663332/vm_memory_map_760.txt)
