Apply hiddenapi encoding to java_sdk_library .impl

Adds a ConfigurationName property, and ConfigurationName() method that
allows a library to separate its name (e.g. framework-tethering.impl)
from the name used in the build configuration,
    e.g. ctx.Config().BootJars().

Updates hiddenapi processing to use ConfigurationName() instead of
ctx.ModuleName().

Changes java_sdk_library to set the ConfigurationName property
of the implementation library to the name of the module instead of
<module>.impl so that it will match the name in the boot jars list.

Bug: 159683330
Test: m framework-tethering
      dexdump ${PRODUCT_OUT}/apex/com.android.tethering/javalib/framework-tethering.jar | grep hiddenapi | wc -l
      Verify that there are >0 hiddenapi entries.
      Add java_sdk_library_import prefer=true for framework-tethering
      and repeat the above to verify that there are 0 hiddenapi entries.
      Apply this change, repeat above and verify that there are the same # of entries as before.
      Remove the prebuilt for framework-tethering
      Repeat the above and verify that there is no change to the # of entries
