This is needed so that we can use non skia supplied vk_mem_alloc.h on clients that have already updated to newest version. As we transition to Bazel builds this helps to make it so we can set the rules for specific clients around VMA without things breaking Bug: skia:13211 Change-Id: I5d38a3a91a44f6b3fdf75894a3248ee3991dd5d9 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/531157 Reviewed-by: Kevin Lubick <kjlubick@google.com>
