draw_state: Add validation extension record

To make things easier for applications the validation
layers will advertise support for two extensions.
The named extension (i.e. DRAW_STATE) is used if the
app only wants to enable this specific layer / extension.
If an app wants to enable all Validation layers they
simply include all VkExtensionProperties who's name is
"Validation". This patch adds this extension to this
layer.
