Add a macro to get string of the backing source memory type, so that

Coincidentally, I sent out a change last week to do the same thing:
"KVM: selftests: Add backing src parameter to dirty_log_perf_test"
(https://lkml.org/lkml/2021/2/2/1430)
Whichever way this ends up being implemented, I'm happy to see others
interested in testing different backing source types too.
Thanks Ben! I have a little question here.
Can we just present three IDs (0/1/2) but not strings for users to
choose which backing_src_type to use like the way of guest modes,
That would be fine with me. The string names are easier for me to read
than an ID number (especially if you were to add additional options
e.g. 1G hugetlb or file backed / shared memory) but it's mostly an
aesthetic preference, so I don't have strong feelings either way.
I vote to expose/consume strings, being able to do ".dirty_log_perf_test --help"
and understand the backing options without having to dig into source was super
nice.
.
Fine then:), I will make some change based on
(https://lkml.org/lkml/2021/2/2/1430), thanks!
