RFR 15 8225319: Remove the RMI static stub compiler rmic

[Roger Riggs]

Please review the CSR[1] and changes to remove the RMI static stub 
compiler (rmic).
RMIC was deprecated for removal in JDK 13 [3].

The components modified are:
  - remove the jdk.rmic module
  - remove the jdk.rmic man page
  - remove all tests of rmic or relying on rmic
  - update or remove makefiles to remove references and dependencies on rmic
  - update source files in java.rmi module to remove extraneous 
references to rmic
