enbale GraphicsContext support in wxGTK28

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello,
I'm working on packaging an application (opencpn) which requires a wxGTK
compiled with GraphicsContext support. So I propose to enable it in
x11/wxGTK28. AFAIK it shouldn't cause problems (linux distributions seems
to have it enabled by default). The attached patch does this, and bump
PKGREVISION for wxGTK28 and wxGTK28-contrib.
Packages dependant on them shouldn't need a PKGREVISION bump because the
ABI should be backward-compatible (kicad is still working fine for me,
with the new wxGTK28 package).

Any objection ?
I'm waiting on this to commit opencpn.
