RFR: JDK-8033236 Update GensrcCharsetMapping.gmk to build-infra standards

[Mike Duigou]

I can't verify that the changes are correct but the resulting build does seem to work for me.

Can you remove this (now) inaccurate comment in Hasher.java :

  46     // This class cannot, sadly, make use of 1.5 features since it must be
  47     // compiled and run with the bootstrap JDK, which is 1.4.2.

Similar to the compile constructs, we can setup a file (or a bunch of files) which needs different kinds of text transformations. In this case, only the INCLUDE functionality is used.
