[11u] RFR: 8212028: Use run-test makefile framework for testing in Oracle's Mach5

[Langer, Christoph]

Hi,

please help reviewing this backport of a build infrastructure change to jdk11u.

One reason for doing this is parity with Oracle's 11.0.6 but the patch also contains some test improvements which will help stabilizing 11u testing. This mainly means increasing some test timeouts for a few tests that tend to timeout on slow or busy test hardware.

The patch mostly applies, apart from these two rejects:
make/RunTests.gmk: http://cr.openjdk.java.net/~clanger/webrevs/8212028.11u-dev.0/8212028-RunTests.gmk.rej
make/RunTestsPrebuilt.gmk: http://cr.openjdk.java.net/~clanger/webrevs/8212028.11u-dev.0/8212028-RunTestsPrebuilt.gmk.rej
So, when reviewing, please have the most thorough look at these places.

I ran the fix through our nightly tests and didn't find regressions. I'm planning to push backport JDK-8213005 together with this change, as it fixes a regression for it.

Bug: https://bugs.openjdk.java.net/browse/JDK-8212028
Original Change: http://hg.openjdk.java.net/jdk/jdk/rev/28375a1de254

Thanks
