render/vulkan: fix VkPushConstantRange for wlr_vk_frag_texture_pcr_data

Browse source 
We pass an alpha multiplier plus a luminance multiplier now.

Fixes the following validation layer error:

    vkCmdPushConstants(): is called with
    stageFlags (VK_SHADER_STAGE_FRAGMENT_BIT), offset (80), size (72)
    but the VkPipelineLayout 0x510000000051 doesn't have a VkPushConstantRange with VK_SHADER_STAGE_FRAGMENT_BIT.
    The Vulkan spec states: For each byte in the range specified by offset and size and for each shader stage in stageFlags, there must be a push constant range in layout that includes that byte and that stage (https://docs.vulkan.org/spec/latest/chapters/descriptorsets.html#VUID-vkCmdPushConstants-offset-01795) (VUID-vkCmdPushConstants-offset-01795)
