[Mesa-dev] [PATCH v4 3/9] anv: Implemented the vkGetPhysicalDeviceMultisamplePropertiesEXT

[Eleni Maria Stea]

Implemented the vkGetPhysicalDeviceMultisamplePropertiesEXT according to
the Vulkan Specification section [36.2. Additional Multisampling
Capabilities].

v2: 1- Moved the vkGetPhysicalDeviceMultisamplePropertiesEXT from the
       anv_sample_locations.c to the anv_device.c (Jason Ekstrand)
    2- Simplified the code that sets the grid size (Jason Ekstrand)
    3- Instead of filling the whole struct, we only fill the parts we
       should override (sType, grid size) and we call
       anv_debug_ignored_stype to any pNext elements (Jason Ekstrand)
