-Re enabled the identify tool for rasters

-The current logic only enabled the identify tool if the raster had a provider with the capability, GDAL datasets do not have a provider per se
-Note the current logic for enabling the identify tool (and other tools?) needs to be re evaluated, as it is done when the layer is loaded not when it is activated/selected
