Update depreciated function usage to new api

[DakJaniels]

The function GetTexCoordsForRole has been deprecated and replaced with GetTexCoordsByGrid.

To test for deprecated functionality, you can disable the Blizzard Addon, Blizzard_Deprecated. This can be done by executing the command /run C_AddOns.DisableAddOn("Blizzard_Deprecated") followed by /reload. Prior to the changes made in this pull request, executing these commands would result in the error message described below. This pull request resolves this issue by replacing the deprecated function with the updated one.
