Fix geometry mojo build dependencies

Everything using Rect in mojom files will indirectly need
to include //ui/gfx/geometry/mojo/geometry_struct_traits.h"
and for that to be allowed in gn, its build target
(//ui/gfx/geometry/mojo:struct_traits) needs to be a public

This fixes about 200 dependency errors as reported by a gn
that can check dependencies in generated files (gn:57).
