This avoids having to manually specify include/legacy_gal
in and legacy GAL targets, and harominizes with legacy_wx.
This also means .cpp files in common/legacy_gal do not
need to specify the legacy_gal subdirectory, so they
will continue to work as needed when legacy_wx is removed.
Dynamic casts should only be used when we explicitly check for the
resulting pointer to be NULL. Where we know the class is castable we
can use static_cast, save on overhead and ensure our resulting pointer
is non-null.
Block rotate and mirror now work like they do in Pcbnew (that is
they're treated as part of the block move/duplicate/whatever
rather than finishing it).

Note: it's only the renderer that is changed from wxDC to GAL. Tools stay the same, consider this a temporary hack.
This commit splits the EDA_DRAW_FRAME, EDA_DRAW_PANEL and BLOCK_SELECTOR classes into two variants, each independently compiled into a static library.
- "legacy_wx" for PCBnew/Gerbview - wxDC-based legacy canvas. We have full GAL support there anyway so it makes no sense to introduce GAL rendering API to the legacy tools.
- "legacy_gal" for EEschema and the rest - GAL-based legacy canvas, using legacy tools but with a GAL renderer.
Such split ensures only a small part of the common library and eeschema is affected, without messing around with already GALified tools.
The commit also removes some header dependencies on class_drawpanel.h
