<Swing Dev> [9] Review request for 8136366 Add a public API to create a L&F without installation

[Alexandr Scherbatiy]

Hello,

Could you review the fix:
   bug: https://bugs.openjdk.java.net/browse/JDK-8136366
   webrev: http://cr.openjdk.java.net/~alexsch/8136366/webrev.00

   Some Swing L&Fs are not public. It is not possible to create them 
using reflection now in JDK 9 because of the modularization feature.

   There are use cases when some information should be obtained from a 
L&F without its installation
    - check if L&F is supported
    - take some defaults to use it in custom L&F

   The proposed solution adds UIManager.createLookAndFeel(className) 
method which allows to create a given L&F without installation.

  Thanks,
  Alexandr.
