[freetype2] master 5f19f49c8 1/2: [truetype] Move deallocation of `DeltaSetIdxMap` into own function.

[Werner Lemberg]

branch: master
commit 5f19f49c81d99ced0499cb3196139beb081dbfd0
Author: Dominik Röttsches <drott@chromium.org>
Commit: Werner Lemberg <wl@gnu.org>

    [truetype] Move deallocation of `DeltaSetIdxMap` into own function.
    
    This is a preparation for handling `DeltaSetIdxMap` and `VarStore` as a
    FreeType service.
    
    * src/truetype/ttgxvar.c (ft_var_done_delta_set_index_map): New function.
    (tt_done_blend): Use it.
