* UVs in lightmap density view were shifting after building lighting. Fixed by considering the padding even if lightmap data is invalid
* Auto generated lightmap UV was snapping charts to the whole padded lightmap instead of the actual valid center region. Fixed by subtracing 2 texels from the packing resolution
* Also fixed some merging conflicts of auto gen

The IMPLEMENT_MODULE macro now defines an empty function called IMPLEMENT_MODULE_{ModuleName}, to which we force a reference to via the linker command line. This behavior can be disabled on a per-module basis by setting bRequiresImplementModule = false from a .build.cs file.

Add a generic opaque mesh view interface FLayoutUV::IMeshView to abstract mesh data access and allow FLayoutUV to be used with any mesh type in any module.
Replaced few instances of using an old version of overlapping corners data structure (multi-map) with new specialized FOverlappingCorners container.
