[SYCL] Squash revision history and remove resolved issue

For our first beta release we should just be at revision 1,
then  later updates to a merged spec can bump this when we
feel is appropriate.

This patch also removes the issue about whether executable
graph update is valuable to users, as we've found evidence of the equivalent
CUDA functionality in pytorch, tensorflow, and GROMACS. Removing this
open issue closes #8
