RFR(JDK 13/java.xml) 8187697: Cleanup: irrelevant code in OutputPropertiesFactory

[Joe Wang]

Please review a cleanup patch for the OutputPropertiesFactory.

The original intention was to remove the (awkward) JDK 1.2-related code, 
line 235-258 in the old file.  I then went a bit further to remove 
another nuisance that annoyed users with an error "Could not load the 
property file 'output_xml.properties' for output method 'xml'" from time 
to time. The output properties files are now removed and the contents 
moved into static arrays in OutputPropertiesFactory between line 192 and 
288 in the new file.

The processing process is kept mostly as is. The only change was 
removing the "fixupPropertyString" process, as a result the only line 
kept from the old file line 447 - 500 was line 376 in the new file.
