Added support for setting the locations when the pipeline has been
created with the dynamic state bit enabled according to the Vulkan
Specification section [26.5. Custom Sample Locations] for the function:
'vkCmdSetSampleLocationsEXT'
The reason that we preferred to store the boolean valid inside the
dynamic state struct for locations instead of using a dirty bit
(ANV_CMD_DIRTY_SAMPLE_LOCATIONS for example) is that other functions
can modify the value of the dirty bits causing unexpected behavior.
v2: Removed all the anv* structs used with sample locations to store
the locations in order for dynamic case. (see also the patch for
the non-dynamic case. (Jason Ekstrand)
