Previously, StaticResourceJars would only find jars with
META-INF/resources content if it had been loaded by a URLClassLoader.
This is not the case on Java 9 and, as a result, static content in
META-INF/resources of any jars on the class path was not found.
This commit updates StaticResourceJars to fall back to using the
JVM's class path to find static resource jars when it was loaded by
a ClassLoader that is not a URLClassLoader.

Previously, DevTools assumed that the TCCL was a URLClassLoader
when trying to determine the URLs that it should examine to determine
the locations that should be watched for triggering a restart. This
fails on Java 9 as the TCCL is not a URLClassLoader.
This commit updates the logic that determines the changeable URLs to
fall back to examining the JVM's class path when the TCCL is not a
URLClassLoader, typically because the application is running on Java
9. This fall back isn't a direct equivalent of the behaviour on Java 8
as the class path of the TCCL and the class path with which the JVM
was launched may not be the same. However, I consider the fix to be
reasonable for two reasons:
1. In reality, the class path of the TCCL and the class path with
which the JVM was launched are the same.
2. There appears to be now to get the URLs on the class path of the
TCCL on Java 9. There is a URLClassPath field, however Java 9's
access restrictions prevent us from using it even if we resort to
reflection.

The translations for the timezone names vary between Java 8 and Java
9. For example, with Java 9, UTC's name is no longer localized while
others have different localizations. This commit updates the test
to verify that the correct locale is being used while also tolerating
the different localization's of Java 8 and 9.

This commit changes the output of a single property to mention the
actual value in the environment as well as the property source that
contributed to the value.
Closes gh-10178
Prior to this commit, if a key was present in multiple PropertySources,
all descriptors shared the same common value. This commit makes sure
that each PropertySource descriptor shows the value it defines rather
than the one that is promoted in the Environment.
