[RFR] [11u] JDK-8232748: "Build static versions of certain JDK libraries"

[Andrew Hughes]

Bug: https://bugs.openjdk.java.net/browse/JDK-8232748
Webrev: https://cr.openjdk.java.net/~andrew/openjdk11/8232748/webrev.01/

This patch adds targets to the build so that static versions of the JDK
native libraries can be built, using static-libs-image. Such static
versions of the libraries are required for consumption by Graal.

With JDK-8210459 now in 11u, this is a largely clean backport, aside
from some context changes, due to additional targets (JCov, JMH) being
present in trunk:

* In make/Bundles.gmk, 11u does not have jcov-bundles
* In make/Main.gmk, 11u does not have jcov-image or jcov-bundles
* In make/autoconf/spec.gmk.in, 11u does not have JMH_CORE_JAR, etc or
JCOV_BUNDLE_NAME.
* In make/conf/jib-profiles.js, the dependencies list in 11u doesn't
include jmh and jcov.

Building the new target, static-libs-image, succeeded. This should have
no effect on other targets.

Thanks,
