8259039: Passing different version to --release flag than javac version output warning

[lahodaj]

For code like:

com.sun.nio.file.ExtendedOpenOption o;

certain combination of command line options produce a proprietary warnings:

$ javac --release 11 T.java 
T.java:2: warning: ExtendedOpenOption is internal proprietary API and may be removed in a future release
    com.sun.nio.file.ExtendedOpenOption o;
                    ^
1 warning

But some do not:

$ javac -source 8 T.java 
warning: [options] bootstrap class path not set in conjunction with -source 8
1 warning

The reason is that the ct.properties files does not mark com.sun.nio.file as proprietary. The proposed fix has two parts:
-adds proprietary to the com.sun.nio.file package in ct.properties
-limits the ct.properties so that it is only used for -source 8. The ct.properties contains 3 types of information: it hides some packages, it marks some packages as "proprietary" (so that they produce the warning), and assigns packages to compact profiles. For -source 9+, most of these is not needed - packages are hidden using the module system, the only packages that need a warning are from the jdk.unsupported module, and there are no compact profiles. So for -source 9+, we don't need to use the ct.properties. (Note none of this applies to --release - it uses a different database.)
