Don't build vulkan_validation_layers on macOS.

angle_enable_vulkan_validation_layers is false on is_mac, so it looks like they were built by accident. Guard the dep on $angle_root/src/common/vulkan:vulkan_validation_layers by angle_enable_vulkan_validation_layers instead of angle_enable_vulkan, and only define the target if angle_enable_vulkan_validation_layers is true (because src/common/vulkan/BUILD.gn gets loaded due to deps on other targets in it, and when a .gn file is loaded all the targets in it get defined). Since vulkan_validation_layers doesn't currently build on arm macs, this happens to fix a build problem there, but it also makes the build on intel macs a bit smaller. This sidesteps comment 13 on the bug. If we ever want to use the validation layers on mac, we'll have to do a real fix then.
