Dispatch table function arguments lose `const` qualifier

[Valakor]

See the generated method DispatchTable::cmdSetBlendConstants(VkCommandBuffer commandBuffer, float blendConstants[4]). The argument blendConstants should be declared as const float blendConstants[4] to match the declaration of PFN_vkCmdSetBlendConstants / vkCmdSetBlendConstants.

As far as I'm aware this is the only method like this and it's easy enough to work around by just calling through the dispatch table's fp_vkCmdSetBlendConstants instead.

Good eye! Not sure how hard it will be to fix, that is one of the annoying parts of autogen using vk.xml cause it requires manually parsing the parameters. But should be straightforward I think.
