RFR: 8143038: [TESTBUG] TestOptionsWithRanges: allow excluding only a subset of tested values specified for a flag

[Dmitry Dmitriev]

Hello,

Please review enhancement to the command line option validation test 
framework.

Currently TestOptionsWithRanges test have several options excluded from 
testing, because these options with big or small values can cause 
problem with testing(create a huge number of threads or consume too much 
memory). This enhancement added ability to exclude max or min values 
from testing and TestOptionsWithRanges was corrected to use this 
enhancement.

Also, in this fix I remove adding negative out-of-range values for the 
unsigned options, because negative values are actual invalid(not 
out-of-range) values for unsigned options.

Testing: tested on all platforms. One of the test was failed on win-64 
platform, but this is not relate to this change. Filled 
https://bugs.openjdk.java.net/browse/JDK-8143249 for that(which seems 
related to the JDK-8069282)

Thanks,
Dmitry
