layer: Validate all features/properties are part of the extension

[spencer-lunarg]

I have found a few cases were

"VkPhysicalDeviceCustomBorderColorPropertiesEXT": {
    "maxCustomBorderColorSamplers": 4294967295
},

is missing while VK_EXT_custom_border_color and VkPhysicalDeviceCustomBorderColorFeaturesEXT are supported

There should be some method to validate all features/properties/format/etc of an extension are listed together in the same profile json
