[8u] RFR: 8241829: Cleanup the code for PrinterJob on windows

[Alex Kashchenko]

Hi,

Please review the backport of JDK-8241829 to 8u:

Bug: https://bugs.openjdk.java.net/browse/JDK-8241829

Original change: https://hg.openjdk.java.net/jdk/jdk/rev/e101dba52342

11u backport: https://hg.openjdk.java.net/jdk-updates/jdk11u-dev/rev/5dc8950e91d5

8u webrev: https://cr.openjdk.java.net/~akasko/jdk8u/8241829/webrev.00/

Patch doesn't apply cleanly because 8u doesn't include changes from
JDK-8027771 (not public, change [1], some details [2]) in
PrintServiceLookupProvider.java. Testing: checked that added test
passes, ran jck:api/javax_print .
