RFR (L) 8044140: [TESTBUG] Create NMT (Native Memory Tracking) tests for NMT2

[Zhengyu Gu]

Hi,

JcmdScale.java:
   There is no change, should not update copyright ...

AutoshutdownNMT.java line #42

42        output.shouldContain("Unrecognized VM option 'AutoshutdownNMT'");

Should be

42        output.shouldContain("Unrecognized VM option 'AutoShutdownNMT'");


Also -XX:-AutoshutdownNMT => -XX:-AutoShutdownNMT
