"Un"-deprecate java_get() and java_set() functions (bug #41239). * java_get.m, java_set.m: move from scripts/deprecated into scripts/java. These are being un-deprecated because there is no alternative for them yet. These functions never existed as m .files, they were previously loadable functions, now __java_set__ and __java_get__, which were removed with 4698ea77aa75.

## @deftypefn {Loadable Function} {@var{val} =} java_get (@var{obj}, @var{name})
## Get the value of the field @var{name} of the Java object @var{obj}.  For
## static fields, @var{obj} can be a string representing the fully qualified
## name of the corresponding class.
## 
## When @var{obj} is a regular Java object, structure-like indexing can be
## used as a shortcut syntax.  For instance, the two following statements are
## equivalent
## 
## @example
## @group
##   java_get (x, "field1")
##   x.field1
## @end group
## @end example
## 
## @seealso{java_set, javaMethod, javaObject}
## @end deftypefn
