[jdk11u-dev] RFR: 8337506: Disable "best-fit" mapping on Windows command line

[Ekaterina Vergizova]

I'd like to backport this for parity with 11.0.29-oracle.
CSR JDK-8349538 has been approved for 11u.
17u patch applies cleanly, but the test requires a few modifications to work properly:
- replaced `native.encoding` property with `file.encoding`, as `native.encoding` is not present in 11u. 
These two are identical unless `file.encoding` is overridden on the command line:
https://github.com/openjdk/jdk17u-dev/blob/master/src/java.base/share/classes/jdk/internal/util/SystemProps.java#L72
- replaced `"str".formatted(args)` with `String.format("str", args)`, as String::formatted() is not available in 11u. Both methods produce the same result.

The new test passes successfully after applying the patch.
