ALF Boundary Issues

Description

1.) Enabling JVET-P0551 disables the macro JVET_O0625_ALF_PADDING. This has the side-effect of disabling the JVET_P0158_ALIGN_ALF_VB changes.

2.) I believe the JVET-P0551 isCrossedByVirtualBoundaries( ) slice boundary detection may be missing logic to detect and pad top-left or bottom-right slice edges. For example, when the top and left CTU are both within the current slice, but the top-left CTU is not. These cases can happen with raster-scan slices.

1) P0158 integration is missing when O0625 is disabled. A merge request has been submitted (https://vcgit.hhi.fraunhofer.de/jvet/VVCSoftware_VTM/merge_requests/1163). Please check if it is correct.

2) yes, boundary processing for raster-scan slices is missing in P0551 integration. However, I believe that P0053, P0157 and P0551 are only related to rectangular slices.

Yes, I believe that should fix the first item. Thanks for looking into the issue.
