@brief Device feature
@m_since_latest

Contains information stored in the @type_vk{PhysicalDeviceFeatures2} structure
chain. Values correspond to equivalently named structure fields, usually just
with the first letter uppercase instead of lowercase.
@see @ref DeviceFeatures, @ref DeviceProperties::features()

@todo @type_vk{PhysicalDeviceVulkan12Features} additionally has
    `samplerMirrorClampToEdge`, `drawIndirectCount`, `descriptorIndexing`,
    `samplerFilterMinMax`, `shaderOutputViewportIndex`, `shaderOutputLayer`, `subgroupBroadcastDynamicId` that aren't exposed in any extension -- does
    that mean we have to enable such extension even on 1.2 in order to enable
    those? Provide some compatibility, as in show them as supported when
    the exts are present and enable corresponding exts when those get enabled
    on device creation?
