[texture] Consolidate the quality to filter conversions

Browse Source 
To convert from a TextureQuality to a COGL filter enumeration
we need to perform two function calls. Since we need both filters
when calling cogl_texture_set_filters() we can safely consolidate
the two conversion functions into one. This also allows using a
shorter function name, thus reducing the lenght of the lines
involved and, more importantly preventing Emmanuele from crying.
