[XProto] Remove usage of all Xlib headers
This CL removes <X11/Xlib.h> from //ui/gfx/x/x11.h. What was provided
by Xlib.h is now provided with inline declarations. The intent is
that I'll incrementally remove declarations from x11.h until there's
nothing left, at which point the dependency on Xlib will be removed and
therefore x11.h can be removed. Doing it this way will ensure no
additional usages of Xlib are introduced, and it gives a nice way of
tracking progress as usages are removed.
* All Xlib macros are now gone, so it's safe to remove the XProto
"undef" files.
* For some usages of Xlib (events in particular), it's easier to port
to XProto now rather than add declarations to x11.h.
* ui/gfx/x/keysyms/keysyms.h is added in its own directory because
it's needed by xkbcommon code, which is also built on ChromeOS, but
ui/gfx/x/BUIDL.gn asserts that the platform is desktop Linux.
