Add back support for `VkFormatFeatureFlagBits2`

[teoxoy]

In #12 we added support for VkFormatFeatureFlagBits2 but we then reverted it in #13 since the data from vulkan.gpuinfo.org was wrong.

Reports with version 3.3 or higher now contain the correct data (SaschaWillems/vulkan.gpuinfo.org#50) and so we could add back support for VkFormatFeatureFlagBits2.

Since we can't interpret the reports prior to version 3.3 for the purposes of querying VkFormatFeatureFlagBits2 we probably need a way to specify a minimum report version, if the minimum passed to the CLI is 3.3 then we can query it.

SGTM. It's fine to special case something in the json loader, like, we merge in the v2 flags but only if the report's version is >=3.3.
