This occurs when running a chromeos build on Linux also and is very spammy/annoying.

Upgrading to P1 since this is blocking a P1 bug

gl: Avoid calling SetRelyOnImplicitSync where not implemented.

crrev.com/485294 introduced a workaround that calls SetRelyOnImplicitSync
on a GLSurface (or a derived class).
The only GLSurface that supports the workaround is GbmSurfaceless
that is instantiated only on CrOS when using Ozone.

This CL avoid calling SetRelyOnImplicitSync since it causes to hit
a NOTIMPLEMENTED on platform where a GLSurface itself is
instantiated.

gl: Remove NOTIMPLEMENTED from GLSurface::SetRelyOnImplicitSync.

GLSurface::SetRelyOnImplicitSync was added to implement a workaround
on CrOS/Intel.

Initially that method was expected to be called only on GbmSurfaceless
that extends GLSurface.

https://chromium-review.googlesource.com/c/565842/ restricted the method
call only to platforms where the workaround is enabled.

Turns out that on Intel on CrOS we still allocate other types of
GLSurfaces. SurfacelessEGL is allocated as an offscreen surface.

In debug builds, where the target_os is chromeos and ozone is not used
we also end up allocating GLSurfaces that are not derived from
GbmSurfaceless, effectively calling GLSurface::SetRelyOnImplicitSync
and hitting the NOTIMPLEMENTED.

This CL removes NOTIMPLEMENTED from GLSurface::SetRelyOnImplicitSync
since it's fine in the scenarios described above to ignore the call
if the surface doesn't support it.
