rhi: vulkan: Enable features on the device

Browse Source 
The silly fine-grained enabling of features on the VkDevice
seems to be ignored in practice by the implementations, but
wideLines becomes relevant because the validation layers warns
if a line width is set on the pipeline without enabling the feature
on the device. So to play nice, enable the features we care about.
