RFR  8207846: Generalize the jdk.net.includeInExceptions security property

It is important to be clear about how whitespace is treated and within
the java.security file
there are other uses that explicitly define how whitespace is used.
I am more concerned about how command line properties are understood and
used how we have to document them.
Allowing whitespace quickly gets bogged down in how shells handle
quotes, telling people they have to
quote them and when/whether you have to quote the quotes.
Having a consistent treatment of command line and security properties
story simple and easier to support.
The jdk.serialFilter property had the same issue and is explicit in the
that spaces are just another character and are not treated specially.
Its a slippery slope, if we start compensating/ignoring whitespace in
then we will have to keep explaining how some are treated differently.
I would keep the original non-whitespace description.
Case-insensistive compares are another slippery slope but make a bit
more sense for usability.
