ENH: Cleanup Find* modules with new HINTS feature

  - The find_* commands now provide a HINTS option.
  - The option specifies paths to be preferred over the system paths.
  - Many Find* modules were using two find calls with NO_DEFAULT_PATH
    to approximate the behavior, but that blocked users from overriding
    things with CMAKE_PREFIX_PATH.
  - This commit uses the HINTS feature to get desired behavior in
    only one find command call.

-# all calls to FIND_PROGRAM/PATH/LIBRARY() follow the same scheme:
