John Stiles 3e6e29cf2e Convert 0 and NULL to nullptr.
The goal was to enable -Wzero-as-null-pointer-constant. Unfortunately,
this was thwarted by VK_NULL_HANDLE which is defined as 0ULL in the
Vulkan headers. It might be possible to enable the warning for a subset
of Skia, but not for the parts which interface with Vulkan.
