RFR: JDK-8256864: [windows] Improve tracing for mapping errors [v4]

[Thomas Stuefe]

> To analyze JDK-8256729 further, we need more tracing:
> 
> 1) We should print all mappings inside the split area if os::split_reserved_memory() fails
> 
> 2) The print-mapping code on windows has some shortcomings:
> - should not probe for mappings outside of what we know are valid address ranges for Windows
> - should handle wrap-arounds - it should be possible to print the whole address space
> - Protection information is printed wrong (MEMORY_BASIC_INFORMATION.Protect would be the correct member)
> - should be printed in a more compact manner - base address should be on the same line as the first region
> - maybe adorned with some basic range info, e.g. library mappings
