RFR: 8264881: Remove the old development option MemProfiling

[Yi Yang]

MemProfiler is a very old development option added at:

^As 00018/00000/00000
^Ad D 1.1 98/04/14 13:18:32 renes 1 0
^Ac date and time created 98/04/14 13:18:32 by renes
^Ae

Today it doesn't work because it is untested and there is no reason/scenario to prove it is useful.

After a short discussion in https://github.com/openjdk/jdk/pull/3340, I'd like to propose removing the memprofiler if there are no strong objections.

Thanks!
Yang
